CVE-2026-80913

A flaw was found in the Linux kernel's SELinux subsystem. An attacker with local access could exploit this by providing a specially crafted SELinux policy. This policy, containing an incorrect number of defined boolean values, would cause the kernel to attempt to access an invalid memory location...

CVE-2026-80912

A flaw was found in the Linux kernel's SELinux subsystem. When processing security class values, the securitygetclasses function could return a null pointer if a class value was not properly defined by the security policy. This could lead to a null pointer dereference, potentially causing a syste...

CVE-2026-80892

A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System component. On systems with a high number of processing units, mounting a specially crafted EROFS image can cause the kernel to allocate an excessive amount of memory for LZMA decompression streams. This uncontrolled memor...

CVE-2026-80888

A flaw was found in the drm/vmwgfx component of the Linux kernel. An unprivileged client can exploit this vulnerability by passing a specially crafted file descriptor fd to the DRMVMWGBSURFACEREF or DRMVMWGBSURFACEREFEXT paths. This can lead to a dmabuf reference leak, causing resource exhaustion...

CVE-2026-80876

A flaw was found in the Linux kernel's ring-buffer component. When 8-byte alignment is enforced, the system incorrectly calculates the length of small events. This error causes these events to report a data length that is 4 bytes larger than their actual size. This discrepancy can lead to...

CVE-2026-80884

A flaw was found in the Linux kernel's NTB Non-Transparent Bridge module. This vulnerability arises from the incorrect handling of Direct Memory Access DMA addresses during memory deallocation. The DMA API requires that the dmafreeattrs function receives the exact dmahandle originally provided by...

CVE-2026-80873

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine component on ARM64 systems. When a nested guest hypervisor L2 encounters a System Error SError exception, the ESREL2 register, which provides details about the exception, is not properly updated. This can cause the guest L2...

CVE-2026-80870

A flaw was found in the Linux kernel's drm/amdkfd component. A local user could provide a specially crafted ID during the Checkpoint/Restore in Userspace CRIU restore process. If this restored ID is larger than the maximum integer value INTMAX, it can trigger a kernel warning. This warning may le...

CVE-2026-80866

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication subsystem. A busy-wait loop in the tipcexitnet function, intended to wait for UDP bearer cleanup, can consume excessive CPU cycles. This issue arises when the condresched function is ineffective, such as when a...

CVE-2026-80845

A flaw was found in the Linux kernel's xfrm IPSec framework component. A lock inversion vulnerability exists within the natkeepalivework function. This flaw can lead to an AB-BA deadlock when a Network Address Translation NAT keepalive worker races with Security Association SA deletion. The...

CVE-2026-80861

A flaw was found in the Linux kernel's USB eXtensible Host Controller Interface xHCI driver. When an xHCI host controller is inaccessible during its setup process, the driver attempts to read from an incorrectly calculated memory address. This unaligned memory access can cause a kernel panic,...

CVE-2026-80828

A flaw was found in the ALSA Advanced Linux Sound Architecture USB audio driver in the Linux kernel. When a system resume operation fails for a USB audio device, the driver's error handling is incomplete. This can leave the audio card in an unusable state, blocking further control access and...

CVE-2026-80786

A flaw was found in the fbdev subsystem of the Linux kernel. This vulnerability occurs because certain user-invoked display mode changes, specifically those not using the FBIOPUTVSCREENINFO ioctl, fail to properly update the fbcon state. A local user could potentially exploit this by triggering a...

CVE-2026-80815

A flaw was found in the ALSA scarlett2 driver in the Linux kernel. This issue arises from the driver's improper management of Universal Serial Bus Request Blocks URBs for notification endpoints, where an already allocated URB is reused without proper re-initialization. This can lead to a system...

CVE-2026-80820

A flaw was found in the Linux kernel's XFS filesystem. A local attacker could trigger a livelock condition during an online file system check fsck if an unlinked inode list contains a loop. This vulnerability could lead to a Denial of Service DoS, making the system unresponsive...

CVE-2026-80742

A flaw was found in the Linux kernel's afpacket Address Family Packet component. A local attacker could exploit this vulnerability by sending specially crafted zero-byte packets through the TPACKET ring buffer on devices without a hard header. This improper handling of zero-length packets can cau...

CVE-2026-80744

A flaw was found in the Linux kernel's netfilter component. Under low-memory conditions, the nftablesoffload module incorrectly triggers warnings for expected memory allocation failures during network packet filtering. This can lead to excessive logging of non-critical errors, potentially impacti...

CVE-2026-80739

A flaw was found in the Linux kernel. A race condition exists in the net/mlx5e driver's Traffic Control TC flow deletion mechanism. When a flow fails to be added, the deletion process attempts to acquire a lock without proper checks, leading to a recursive lock acquisition in certain 'peer flow'...

CVE-2026-80733

A flaw was found in the Linux kernel's networking component. When processing network packets via raw or packet sockets over virtual devices, the skmcloop function could incorrectly trigger a WARNONONCE message. This occurred because the function did not properly handle non-INET Internet Protocol...

CVE-2026-80730

A flaw was found in the Linux kernel. The ring-buffer component's cleanup routine can incorrectly attempt to stop a kernel thread using an invalid error pointer. This happens when kthreadrunoncpu fails, storing an error pointer in the rbthreads array. Calling kthreadstop on this invalid pointer...
