CVE-2026-68113
Description
A flaw was found in the Linux kernel's drm/amdgpu/gfx12 component. This vulnerability allowed a local attacker to trigger a kernel crash due to an improper use of the BUG_ON() macro, which is designed to halt the system on critical errors. By replacing BUG_ON() with WARN_ON(), the kernel no longer crashes, mitigating a potential Denial of Service (DoS) condition.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker that can trigger an assert statement can still lead to a denial of service if the relevant code can be triggered by an attacker, and if the scope of the assert() extends beyond the attacker's own session.
