CVE-2026-68109

A flaw was found in the Linux kernel, specifically within the drm/amdgpu/sdma7.1 component. This vulnerability occurs when a BUGON macro is triggered, which can lead to an immediate kernel crash. An attacker could potentially exploit this to cause a Denial of Service DoS on the affected system...

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...

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...

CVE-2026-68315

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. When processing a Stream Reset Incoming Request RESETINREQUEST from a peer, the kernel does not properly validate the stream count. This can lead to an integer overflow when calculating the size for t...

CVE-2026-68239

A flaw was found in the Linux kernel's Direct Rendering Manager drm/ttm component. A local attacker could trigger a null pointer dereference by manipulating memory pages in ttmpoolbackup. This vulnerability occurs because the system attempts to process or free memory pages that are either empty...

CVE-2026-68426

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...

CVE-2026-68201

A flaw was found in the ALSA Advanced Linux Sound Architecture timer component of the Linux kernel. When a master timer instance is closed, it does not properly ensure that all associated slave timer callbacks have finished executing before detaching them. This oversight can lead to a...
