Out-of-bounds read in Linux kernel - CVE-2026-53205

Vulnerability identifier: #VU135572

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-53205

CWE-ID: CWE-125

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to an out-of-bounds read in the firmware log buffer handling in drivers/accel/ivpu/ivpu_fw_log.c when processing firmware-supplied log indices. A local user can supply invalid read or write indices to trigger out-of-bounds buffer access and cause a denial of service.

Exploitation requires firmware to provide invalid log buffer index values.
