About this tag
The vbios parsing tag covers technical reporting on how graphics firmware is read during GPU initialization, with current coverage focused on AMD Linux kernel handling. Tagged content examines a vulnerability in the Display Core code, where malformed or malicious AMD GPU VBIOS data can cause an out-of-bounds read while processing GPIO pin lookup-table entries. It also explains the upstream fix: validating the complete table size before iteration, along with the vulnerability’s high severity rating and backports to supported kernel branches. This page is relevant to readers tracking GPU firmware behavior, Linux graphics security, kernel updates, and safe handling of AMD VBIOS data.

    CVE-2026-64097 Fix: Update AMD Linux GPU Kernels

    CVE-2026-64097 is a newly published Linux kernel vulnerability in AMD’s Display Core code that turns a seemingly routine firmware-parsing mistake into a potentially serious local security issue: a malformed or malicious AMD GPU VBIOS can cause the kernel to read beyond the mapped BIOS image...
