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

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 535da9ad8420c3b686a642403d4147ff220255fd, 5961c703414048f46818be8bbb11075a9a63fb4e, 6.12.94.

Low priority for now. Upgrade to Linux Linux 535da9ad8420c3b686a642403d4147ff220255fd, 5961c703414048f46818be8bbb11075a9a63fb4e, 6.12.94 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
