CVE-2026-53205
Published: June 25, 2026· Updated: Jun 30, 2026
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.
Technical Analysis
CVE-2026-53205 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), availability disruption (denial of service), with a CVSS base score of 7.1.
