CVE-2025-0624 1 Redhat 7 Enterprise Linux, Openshift, Rhel Aus and 4 more 2025-09-19 7.6 High
A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot information, which can be used to by-pass secure boot protections.
CVE-2023-27349 2 Bluez, Redhat 2 Bluez, Enterprise Linux 2025-09-19 8.0 High
BlueZ Audio Profile AVRCP Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code via Bluetooth on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious device. The specific flaw exists within the handling of the AVRCP protocol. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-19908.
CVE-2025-10528 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2025-09-18 7.3 High
This vulnerability affects Firefox < 143, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3.
CVE-2024-45336 1 Redhat 8 Acm, Ceph Storage, Enterprise Linux and 5 more 2025-09-18 6.1 Medium
The HTTP client drops sensitive headers after following a cross-domain redirect. For example, a request to a.com/ containing an Authorization header which is redirected to b.com/ will not send that header to b.com. In the event that the client received a subsequent same-domain redirect, however, the sensitive headers would be restored. For example, a chain of redirects from a.com/, to b.com/1, and finally to b.com/2 would incorrectly send the Authorization header to b.com/2.
CVE-2024-27404 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 4.7 Medium
In the Linux kernel, the following vulnerability has been resolved: mptcp: fix data races on remote_id Similar to the previous patch, address the data race on remote_id, adding the suitable ONCE annotations.
CVE-2024-27403 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel E4s and 1 more 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_flow_offload: reset dst in route object after setting up flow dst is transferred to the flow object, route object does not own it anymore. Reset dst in route object, otherwise if flow_offload_add() fails, error path releases dst twice, leading to a refcount underflow.
CVE-2023-6841 1 Redhat 7 Jboss Enterprise Bpms Platform, Jboss Fuse, Keycloak and 4 more 2025-09-18 7.5 High
A denial of service vulnerability was found in keycloak where the amount of attributes per object is not limited,an attacker by sending repeated HTTP requests could cause a resource exhaustion when the application send back rows with long attribute values.
CVE-2023-52658 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: Revert "net/mlx5: Block entering switchdev mode with ns inconsistency" This reverts commit 662404b24a4c4d839839ed25e3097571f5938b9b. The revert is required due to the suspicion it is not good for anything and cause crash.
CVE-2024-27397 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Rhel Aus and 3 more 2025-09-18 7.0 High
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: use timestamp to check for set element timeout Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue.
CVE-2024-1139 1 Redhat 2 Acm, Openshift 2025-09-18 7.7 High
A credentials leak vulnerability was found in the cluster monitoring operator in OCP. This issue may allow a remote attacker who has basic login credentials to check the pod manifest to discover a repository pull secret.
CVE-2024-27389 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: pstore: inode: Only d_invalidate() is needed Unloading a modular pstore backend with records in pstorefs would trigger the dput() double-drop warning: WARNING: CPU: 0 PID: 2569 at fs/dcache.c:762 dput.part.0+0x3f3/0x410 Using the combo of d_drop()/dput() (as mentioned in Documentation/filesystems/vfs.rst) isn't the right approach here, and leads to the reference counting problem seen above. Use d_invalidate() and update the code to not bother checking for error codes that can never happen. ---
CVE-2021-47544 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Rhel Aus and 3 more 2025-09-18 5.9 Medium
In the Linux kernel, the following vulnerability has been resolved: tcp: fix page frag corruption on page fault Steffen reported a TCP stream corruption for HTTP requests served by the apache web-server using a cifs mount-point and memory mapping the relevant file. The root cause is quite similar to the one addressed by commit 20eb4f29b602 ("net: fix sk_page_frag() recursion from memory reclaim"). Here the nested access to the task page frag is caused by a page fault on the (mmapped) user-space memory buffer coming from the cifs file. The page fault handler performs an smb transaction on a different socket, inside the same process context. Since sk->sk_allaction for such socket does not prevent the usage for the task_frag, the nested allocation modify "under the hood" the page frag in use by the outer sendmsg call, corrupting the stream. The overall relevant stack trace looks like the following: httpd 78268 [001] 3461630.850950: probe:tcp_sendmsg_locked: ffffffff91461d91 tcp_sendmsg_locked+0x1 ffffffff91462b57 tcp_sendmsg+0x27 ffffffff9139814e sock_sendmsg+0x3e ffffffffc06dfe1d smb_send_kvec+0x28 [...] ffffffffc06cfaf8 cifs_readpages+0x213 ffffffff90e83c4b read_pages+0x6b ffffffff90e83f31 __do_page_cache_readahead+0x1c1 ffffffff90e79e98 filemap_fault+0x788 ffffffff90eb0458 __do_fault+0x38 ffffffff90eb5280 do_fault+0x1a0 ffffffff90eb7c84 __handle_mm_fault+0x4d4 ffffffff90eb8093 handle_mm_fault+0xc3 ffffffff90c74f6d __do_page_fault+0x1ed ffffffff90c75277 do_page_fault+0x37 ffffffff9160111e page_fault+0x1e ffffffff9109e7b5 copyin+0x25 ffffffff9109eb40 _copy_from_iter_full+0xe0 ffffffff91462370 tcp_sendmsg_locked+0x5e0 ffffffff91462370 tcp_sendmsg_locked+0x5e0 ffffffff91462b57 tcp_sendmsg+0x27 ffffffff9139815c sock_sendmsg+0x4c ffffffff913981f7 sock_write_iter+0x97 ffffffff90f2cc56 do_iter_readv_writev+0x156 ffffffff90f2dff0 do_iter_write+0x80 ffffffff90f2e1c3 vfs_writev+0xa3 ffffffff90f2e27c do_writev+0x5c ffffffff90c042bb do_syscall_64+0x5b ffffffff916000ad entry_SYSCALL_64_after_hwframe+0x65 The cifs filesystem rightfully sets sk_allocations to GFP_NOFS, we can avoid the nesting using the sk page frag for allocation lacking the __GFP_FS flag. Do not define an additional mm-helper for that, as this is strictly tied to the sk page frag usage. v1 -> v2: - use a stricted sk_page_frag() check instead of reordering the code (Eric)
CVE-2024-36019 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 7.1 High
In the Linux kernel, the following vulnerability has been resolved: regmap: maple: Fix cache corruption in regcache_maple_drop() When keeping the upper end of a cache block entry, the entry[] array must be indexed by the offset from the base register of the block, i.e. max - mas.index. The code was indexing entry[] by only the register address, leading to an out-of-bounds access that copied some part of the kernel memory over the cache contents. This bug was not detected by the regmap KUnit test because it only tests with a block of registers starting at 0, so mas.index == 0.
CVE-2024-36015 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ppdev: Add an error check in register_device In register_device, the return value of ida_simple_get is unchecked, in witch ida_simple_get will use an invalid index value. To address this issue, index should be checked after ida_simple_get. When the index value is abnormal, a warning message should be printed, the port should be dropped, and the value should be recorded.
CVE-2021-47566 2 Linux, Redhat 5 Linux Kernel, Rhel Aus, Rhel E4s and 2 more 2025-09-18 7.8 High
In the Linux kernel, the following vulnerability has been resolved: proc/vmcore: fix clearing user buffer by properly using clear_user() To clear a user buffer we cannot simply use memset, we have to use clear_user(). With a virtio-mem device that registers a vmcore_cb and has some logically unplugged memory inside an added Linux memory block, I can easily trigger a BUG by copying the vmcore via "cp": systemd[1]: Starting Kdump Vmcore Save Service... kdump[420]: Kdump is using the default log level(3). kdump[453]: saving to /sysroot/var/crash/127.0.0.1-2021-11-11-14:59:22/ kdump[458]: saving vmcore-dmesg.txt to /sysroot/var/crash/127.0.0.1-2021-11-11-14:59:22/ kdump[465]: saving vmcore-dmesg.txt complete kdump[467]: saving vmcore BUG: unable to handle page fault for address: 00007f2374e01000 #PF: supervisor write access in kernel mode #PF: error_code(0x0003) - permissions violation PGD 7a523067 P4D 7a523067 PUD 7a528067 PMD 7a525067 PTE 800000007048f867 Oops: 0003 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 468 Comm: cp Not tainted 5.15.0+ #6 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.14.0-27-g64f37cc530f1-prebuilt.qemu.org 04/01/2014 RIP: 0010:read_from_oldmem.part.0.cold+0x1d/0x86 Code: ff ff ff e8 05 ff fe ff e9 b9 e9 7f ff 48 89 de 48 c7 c7 38 3b 60 82 e8 f1 fe fe ff 83 fd 08 72 3c 49 8d 7d 08 4c 89 e9 89 e8 <49> c7 45 00 00 00 00 00 49 c7 44 05 f8 00 00 00 00 48 83 e7 f81 RSP: 0018:ffffc9000073be08 EFLAGS: 00010212 RAX: 0000000000001000 RBX: 00000000002fd000 RCX: 00007f2374e01000 RDX: 0000000000000001 RSI: 00000000ffffdfff RDI: 00007f2374e01008 RBP: 0000000000001000 R08: 0000000000000000 R09: ffffc9000073bc50 R10: ffffc9000073bc48 R11: ffffffff829461a8 R12: 000000000000f000 R13: 00007f2374e01000 R14: 0000000000000000 R15: ffff88807bd421e8 FS: 00007f2374e12140(0000) GS:ffff88807f000000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f2374e01000 CR3: 000000007a4aa000 CR4: 0000000000350eb0 Call Trace: read_vmcore+0x236/0x2c0 proc_reg_read+0x55/0xa0 vfs_read+0x95/0x190 ksys_read+0x4f/0xc0 do_syscall_64+0x3b/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xae Some x86-64 CPUs have a CPU feature called "Supervisor Mode Access Prevention (SMAP)", which is used to detect wrong access from the kernel to user buffers like this: SMAP triggers a permissions violation on wrong access. In the x86-64 variant of clear_user(), SMAP is properly handled via clac()+stac(). To fix, properly use clear_user() when we're dealing with a user buffer.
CVE-2024-27056 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Eus 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: ensure offloading TID queue exists The resume code path assumes that the TX queue for the offloading TID has been configured. At resume time it then tries to sync the write pointer as it may have been updated by the firmware. In the unusual event that no packets have been send on TID 0, the queue will not have been allocated and this causes a crash. Fix this by ensuring the queue exist at suspend time.
CVE-2024-27057 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspend When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next boot.
CVE-2025-8067 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2025-09-18 8.5 High
A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor list and index specifying the file where the loop device should be backed. The function itself validates the index value to ensure it isn't bigger than the maximum value allowed. However, it fails to validate the lower bound, allowing the index parameter to be a negative value. Under these circumstances, an attacker can cause the UDisks daemon to crash or perform a local privilege escalation by gaining access to files owned by privileged users.
CVE-2024-27023 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: md: Fix missing release of 'active_io' for flush submit_flushes atomic_set(&mddev->flush_pending, 1); rdev_for_each_rcu(rdev, mddev) atomic_inc(&mddev->flush_pending); bi->bi_end_io = md_end_flush submit_bio(bi); /* flush io is done first */ md_end_flush if (atomic_dec_and_test(&mddev->flush_pending)) percpu_ref_put(&mddev->active_io) -> active_io is not released if (atomic_dec_and_test(&mddev->flush_pending)) -> missing release of active_io For consequence, mddev_suspend() will wait for 'active_io' to be zero forever. Fix this problem by releasing 'active_io' in submit_flushes() if 'flush_pending' is decreased to zero.
CVE-2024-26990 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-18 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Write-protect L2 SPTEs in TDP MMU when clearing dirty status Check kvm_mmu_page_ad_need_write_protect() when deciding whether to write-protect or clear D-bits on TDP MMU SPTEs, so that the TDP MMU accounts for any role-specific reasons for disabling D-bit dirty logging. Specifically, TDP MMU SPTEs must be write-protected when the TDP MMU is being used to run an L2 (i.e. L1 has disabled EPT) and PML is enabled. KVM always disables PML when running L2, even when L1 and L2 GPAs are in the some domain, so failing to write-protect TDP MMU SPTEs will cause writes made by L2 to not be reflected in the dirty log.
