Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx12: replace BUG_ON() with WARN_ON() There's no need to crash the kernel for these cases. (cherry picked from commit f952076f76d62f783e8ba4995a7c400d39354ccf) 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. Red Hat severity: Moderate — CVSS 4.1 (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H).
