A flaw was found in the drm/amdgpu component of the Linux kernel. A use-after-unlock vulnerability exists where a virtual machine (VM) pointer is dereferenced after its protective lock has been released. This allows the pointer to be modified, potentially leading to memory corruption. An attacker could exploit this to cause a denial of service or achieve privilege escalation.

The system must be rebooted for this update to take effect.
Red Hat recommends treating all kernel errata as security-relevant. Given the kernel's fundamental role, any bug has a higher chance of impacting system security, even if that impact only becomes clear after a fix is published. Therefore, Red Hat prioritizes delivering fixes that improve our customers' overall security posture.
