UBUNTU-CVE-2026-43400
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: add upper bound check on user inputs in signal ioctl Huge input values in amdgpuuserqsignalioctl can lead to a OOM and could be exploited. So check these input value against AMDGPUUSERQMAXHANDLES which is big enough...
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 ...
PT-2026-39060
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A reference leak exists in the amdgpu userq wait ioctl function. The issue occurs when the ioctl is aborted because the output array is too small, failing to drop references to the synco...
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...
SUSE CVE-2026-23338
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: Do not allow userspace to trivially triger kernel warnings Userspace can either deliberately pass in the too small numfences, or the required number can legitimately grow between the two calls to the userq wait...
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...

The vulnerability of the amdgpu_userq_restore_worker() function in the drivers/gpu/drm/amd/amdgpu/amdgpu_userq.c driver of the Direct Rendering Infrastructure (DRI) module for AMD GPU cores in the Linux operating system allows a hacker to trigger a service failure.
The vulnerability of the amdgpuuserqrestoreworker function in the drivers/gpu/drm/amd/amdgpu/amdgpuuserq.c driver of the Direct Rendering Infrastructure DRI module for AMD GPU cores in the Linux operating system is related to the reutilization of previously freed memory. Exploiting this...
