CVE-2026-43400

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the drm/amdgpu component where the amdgpu userq signal ioctl function lacks proper upper bound checks on user inputs. Providing excessively large input values can lead to an Out-Of-Memory (OOM) condition, which is a state where the system exhausts its available memory, potentially resulting in a Denial of Service (DoS).

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
