CVE-2026-43298

A flaw was found in the amdgpu graphics driver within the Linux kernel. During deinitialization, the driver attempts to release a Video Core Next (VCN) poison interrupt request (IRQ) on a Virtual Function (VF) even when it was not enabled. This can cause a kernel warning and lead to system instability, potentially resulting in a Denial of Service (DoS).

This vulnerability is rated Low because triggering it requires local administrative access or a specific hardware deinitialization sequence on virtualized AMD GPU instances, producing only a kernel warning rather than arbitrary code execution. Under typical Red Hat Enterprise Linux deployments, the issue only manifests when tearing down or unloading the driver for SR-IOV Virtual Functions utilizing VCN 2.5 hardware. Because exploitation does not facilitate privilege escalation or remote compromise, the overall operational risk to systems is minimal.
