Search: CVE-2026-31488

A vulnerability in the Linux kernel's AMD display driver involves incorrect handling of display mode changes during Display Stream Compression (DSC) validation. This flaw can cause a memory leak and use-after-free error when unrelated mode changes are skipped improperly. A local attacker with the ability to trigger specific display configuration changes could exploit this issue to cause system crashes, denial of service, or potentially escalate privileges. The vulnerability affects Linux kernel version 5.18 and has been fixed in subsequent commits.
