CVE-2026-23264

A flaw was found in the Linux kernel's AMD GPU driver. On systems configured with multiple graphics processing units where only one device supports Active State Power Management (ASPM), improper evaluation of ASPM settings can lead to kernel instability. A local user could exploit this condition to cause a system crash, resulting in a Denial of Service (DoS).

This vulnerability is rated as having a Low impact for Red Hat Enterprise Linux because it requires a highly specific and uncommon multi-GPU hardware configuration to trigger. Exploitation demands local system access and is restricted to environments with mixed AMD graphics adapters where Active State Power Management support differs between installed devices. Typical enterprise servers and virtualized deployments do not utilize disparate dual AMD GPU hardware, thereby substantially limiting real-world exposure to this kernel denial-of-service condition.
