CVE-2026-53205 accel/ivpu: Add bounds checks for firmware log indices

What is CVE-2026-53205?

CVE-2026-53205 is a high-severity memory corruption vulnerability in Linux kernel, published on 25 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-787, CWE-125

Which versions are affected by CVE-2026-53205?

It affects 1 product.

Products include Linux kernel.

How do I fix CVE-2026-53205?

Apply the vendor's patch.

Upgrade to the fixed version. Memory-safe languages, compiler hardening and fuzzing prevent most new cases. More about Memory corruption.
