CVE-2026-97915 PUBLISHED

accel/ivpu: Limit firmware log name prints to field size

Assigner: Linux
Reserved: 25.09.2026 Published: 25.09.2026 Updated: 25.09.2026

In the Linux kernel, the following vulnerability has been resolved:

accel/ivpu: Limit firmware log name prints to field size

The name in struct vpu_tracing_buffer_header is a fixed-size array populated by the NPU firmware. It is expected to be NUL-terminated, but nothing on the host side enforces this, so printing it with an unbounded string conversion would read past the field if the terminator is ever missing and expose adjacent bytes of the shared tracing BO through dmesg and the debugfs FW log output.

Print at most as many characters as the name field holds, so the output never runs past it even if the string is not NUL-terminated.
