Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-06-28 09:31

Details

In the Linux kernel, the following vulnerability has been resolved:

accel/ivpu: Add bounds checks for firmware log indices

Add validation that read and write indices in the firmware log buffer are within valid bounds (< data_size) before using them. If out-of-bounds indices are encountered (from firmware), clamp them to safe values instead of proceeding with invalid offsets.

This prevents potential out-of-bounds buffer access when firmware supplies invalid log indices.

Severity

7.1 (High)
