CVE-2026-45908

A flaw was found in the Linux kernel's accel/amdxdna component. The amdxdnaubufmap function allocates memory for scatter-gather SG and internal SG table structures. However, it fails to free this allocated memory if subsequent operations, such as sgalloctablefrompages or dmamapsgtable, encounter ...

Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the ipmi:si driver failing to restore its state when message allocation fails...

CVE-2026-46224: Missing Release of Memory after Effective Lifetime

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix bo leak in xedmabufinitobj on allocation failure When drmgpuvmresvobjectalloc fails, the pre-allocated storage bo is not freed. Add xebofreestorage before returning the error. xedmabufinitobj calls xeboinitlocked, whi...

CVE-2026-46108: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ipmi:si: Return state to normal if message allocation fails There were places where nothing would get started if a message allocation failed, so the driver needs to return to normal state...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A buffer object bo leak occurs in the xe dma buf init obj function. When drm gpuvm resv object alloc fails, the pre-allocated storage bo is not freed. Because xe gem prime import cannot...

PT-2026-44311

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0.11-1.1 Description A NULL pointer dereference occurs in the octeon ep vf driver. The function napi build skb can return NULL if an allocation failure occurs. In octep vf oq process rx, the result of this...

CVE-2026-45964

A flaw was found in the Linux kernel's SUNRPC Sun Remote Procedure Call gssauth module. An issue in the error handling path for gssallocmsg could lead to a kernel reference count kref leak. This occurs when a memory allocation fails, preventing the proper release of the gssauth structure. A local...

CVE-2026-45998

A flaw was found in the Linux kernel's rxrpc subsystem. This vulnerability arises when the system attempts to unshare a packet buffer, and the operation fails due to an allocation issue. This failure can lead to a Use-After-Free UAF condition, where the system attempts to access memory that has...

CVE-2026-47271

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, src/mem.c implemented out-of-memory guards for xmalloc, xrealloc, and xstrdup using assertdata != NULL. The C standard specifies that all assert expressions are compiled out when NDEBUG is defined at...
