CVE-2026-53205

accel/ivpu: Add bounds checks for firmware log indices

State: Published
Severity: 7.1 High
Published: Jun 25, 2026
Updated: Oct 19, 2026
Reserved: Jun 9, 2026

Description

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.
