CVE-2026-53325

CVE-2026-53325 affects the Linux kernel’s AGP AMD64 driver. The root cause is broken error propagation in agp_amd64_probe(): when no AMD northbridges are found, cache_nbs() returns a negative error code (e.g., -ENODEV), but the probe incorrectly checks for exactly -1. This allows initialization t...
