CVE-2026-97915

/// Technical description

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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
