CVE-2026-53205

Kernel memory disclosure and crash via unchecked indices

Published Jun 25, 2026 · Updated Jun 25, 2026

Out-of-bounds access in the ivpu firmware-log path in Linux Kernel allows local users to read kernel memory or crash the system. The fw_log_print_buffer function uses firmware-supplied read and write indices as log-buffer offsets without first verifying that each is below data_size. Reachability requires low-privileged access to Intel NPU interfaces and invalid firmware log indices; the bounded impacts are memory disclosure and a system crash.
