CVE-2026-68265

A flaw was found in the Linux kernel. Specifically, within the drm/xe/vm module, an out-of-bounds access can occur when handling the DRMXECONSULTMEMADVISEPREFLOC region for a Buffer Object BO Virtual Memory Area VMA. This happens because a value of -1 is incorrectly used as an index into a memory...

CVE-2026-68388

A flaw was found in the Linux kernel's Server Message Block SMB client. The smb3simplefallocaterange function, which manages file allocation, can incorrectly process overlapping allocated ranges provided by a server. This can result in parts of a file not being properly zero-filled, leading to...

CVE-2026-68311

A flaw was found in the Linux kernel's wifi: mt76: mt7925 driver. When handling Multi-Link Operation MLO stations, the mt7925stasetdecapoffload function can attempt to dereference a null pointer if a station link is not properly associated with a Virtual Interface VIF link. This can lead to a...

CVE-2026-68096

A flaw was found in the Linux kernel's audit subsystem. A local user can trigger a recursive locking deadlock by moving a file that has an existing executable audit rule. This occurs when the audit subsystem attempts to acquire a lock that is already held, leading to a system-wide deadlock. This...

kernel: mm/slab: do not limit zeroing to orig_size when only red zoning is enabled

A flaw was found in the Linux kernel's memory management subsystem. This issue occurs when the kernel's memory allocator attempts to zero out newly allocated memory, but an incorrect check prevents the full memory region from being cleared under specific configurations. This can lead to memory no...

kernel: ipc: limit next_id allocation to the valid ID range

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

kernel: fsnotify: Fix ordering of iput() and watched_objects decrement

In the Linux kernel, the following vulnerability has been resolved: fsnotify: Fix ordering of iput and watchedobjects decrement Ensure the superblock is kept alive until we're done with iput. Holding a reference to an inode is not allowed unless we ensure the superblock stays alive, which fsnotif...

kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation

A flaw was found in the Linux kernel's AMD display component. This vulnerability arises from incorrect validation of display mode changes during Display Stream Compression DSC processing. A local attacker could exploit this by initiating specific display configuration changes, which may lead to a...

kernel: futex: Fix UaF between futex_key_to_node_opt() and vma_replace_policy()

A flaw was found in the Linux kernel. A timing issue, known as a race condition, exists within the futex subsystem. This vulnerability could allow a local attacker to access memory after it has been freed, leading to a system crash denial of service or potentially the disclosure of sensitive...

kernel: shmem: fix recovery on rename failures

A flaw was found in the Linux kernel's shmem tmpfs filesystem rename operation. Under severe memory pressure, the mapletree insertion used during file rename can fail, and the error recovery path does not properly handle this failure. This can leave the filesystem directory offset tree in an...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from t...

CVE-2026-68408

A flaw was found in the Linux kernel's wifi: cfg80211 component. A local attacker could trigger a system deadlock by performing specific concurrent operations related to wireless interface management. This race condition occurs when a wireless interface is being torn down while a related network...

CVE-2026-68359

A flaw was found in the Linux kernel's hwmon nzxt-smart2 component. A race condition exists when the hidhwstop function is called without first stopping device input/output IO. If a device probe operation fails after IO has been initiated, this race condition can lead to a use-after-free UAF...

CVE-2026-68313

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. A vulnerability in the tipcnlcompatdumpit function can lead to an infinite loop if a callback returns a negative error code. This prevents the release of a critical system lock, causing other processes to...

CVE-2026-68199

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. This vulnerability allows a local attacker to cause an out-of-bounds memory access. The flaw occurs when the firmware provides an invalid window size during an ADDBA Add Block Ack request, leading to incorrect memory allocation. This can...

CVE-2026-68151

A flaw was found in the Linux kernel's binfmtelffdpic component. This component, which handles FDPIC ELF binaries, does not correctly process multiple PTINTERP program headers. An unprivileged local attacker can exploit this by crafting a malicious binary with more than one PTINTERP header...

CVE-2026-68419

A flaw was found in the Linux kernel's RDMA/irdma component. A local user could exploit this by attempting to re-register specific memory regions Queue Pair, Completion Queue, or Shared Receive Queue objects that are not intended for re-registration. This could lead to an invalid operation being...

CVE-2026-68411

A flaw was found in the Linux kernel's mac80211hwsim component. A malicious backend device could report an oversized receive length to the hwsimvirtiorxwork function. This could cause the system to write past the end of a buffer, leading to a kernel panic and a denial of service DoS for the guest...

CVE-2026-68355

A flaw was found in the ath11k component of the Linux kernel. When processing Wi-Fi wireless fidelity data, a specific function can attempt to access memory outside of its allocated buffer. This buffer underflow occurs if the first entry in a data structure has a zero buffer address, leading to a...
