CVE-2026-74353

A flaw was found in the drm/amdkfd component of the Linux kernel. This vulnerability occurs when the system fails to properly resume all queues after a suspend operation, even if some suspend operations fail. An attacker could potentially exploit this by triggering a scenario where queue removal fails, leading to an unscheduled Graphics Processing Unit (GPU) reset. This could result in a Denial of Service (DoS) for the affected GPU functionality.

A flaw of low impact was found in the AMD KFD (drm/amdkfd) driver of the Linux kernel as shipped in Red Hat Enterprise Linux and Red Hat In-Vehicle OS. The driver did not reliably resume all queues after a suspend_all operation: when suspending some queues failed, otherwise healthy queues could remain suspended, and when queue removal failed, the required GPU reset was not scheduled. A local user with access to the AMD KFD/GPU device could trigger a bad GPU queue condition that leaves good queues suspended, resulting in a denial of service for GPU compute workloads or forcing GPU reset-based recovery. The flaw has no confidentiality or integrity impact and is not network-reachable. The affected streams are Red Hat Enterprise Linux 9 (rhel-9.6.z, rhel-9.8.z, rhel-9.9) and Red Hat Enterprise Linux 10 (rhel-10.0.z, rhel-10.2.z, rhel-10.3), and Red Hat In-Vehicle OS 2 streams derived from them, where the fix is deferred to a later update; the residual risk is a local denial of service limited to AMD GPU functionality. Red Hat Enterprise Linux 7 and 8, and the earlier RHEL 9.2 and 9.4 update streams, do not contain the vulnerable code and are therefore not affected. Although the Red Hat CVSS:3.1 base score is 5.5 (Moderate), Red Hat rates the impact of this flaw as LOW because exploitation is limited to a local denial of service of AMD GPU workloads.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
