CVE-2026-43398

A flaw was found in the Linux kernel's amdgpu graphics driver. A local user could exploit this vulnerability by providing excessively large input values to the amdgpuuserqwaitioctl function. This improper input validation can lead to an Out-Of-Memory OOM condition, resulting in a Denial of Servic...

CVE-2026-43399

CVE-2026-43399 affects the Linux kernel amdgpu driver: a reference leak in amdgpu_userq_wait_ioctl occurs when an ioctl is aborted because the output array is too small. The fix drops references to syncobj and timeline fence during abort, and is cherry-picked from commit 68951e9c3e6bb22396bc42ef2...

CVE-2026-43398

The CVE-2026-43398 entry concerns the Linux kernel amdgpu driver. A vulnerability arises from improper input validation in the userq_wait ioctl (amdgpu_userq_wait_ioctl), where excessively large input values can cause an Out-Of-Memory (OOM) situation, leading to Denial of Service. The root cause ...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of upper-bound checks on user input in the amdgpuuserqwaitioctl function. This...

CVE-2026-23338

A flaw was found in the Linux kernel, specifically within the drm/amdgpu/userq component. This vulnerability allows a local user to intentionally or unintentionally trigger kernel warnings. This occurs when the user provides an incorrect number of fences during a userq wait ioctl operation. While...

CVE-2026-23338

The CVE-2026-23338 issue affects the Linux kernel component drm/amdgpu/userq. Userspace can trigger kernel warnings by providing an incorrect or growing number of fences across a userq wait ioctl, causing a backtrace to be emitted. The fix removes WARN_ONs so that, when the kernel detects nothing...
