Ethosu Job Open Return Value Fix in Linux Kernel

Publication date: 2026-09-25

Last updated on: 2026-09-25

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Fix ethosu_job_open() return value A WARN_ON() returns a 0 or 1, not the original negative errno. Just drop the WARN_ON() as the FD open will pass the return code to userspace and there's only one possible source of the error (drm_sched_entity_init()).

Executive Summary

This vulnerability in the Linux kernel involves a bug in the ethosu_job_open() function where a WARN_ON() statement incorrectly returns a 0 or 1 instead of the original negative error code. The fix removes the WARN_ON() check since the file descriptor open operation will pass the error to userspace, and the only possible error source is drm_sched_entity_init().

Impact Analysis

This vulnerability may cause incorrect error handling during file descriptor operations in the ethosu driver, potentially leading to improper error reporting to userspace. However, the impact is likely limited to specific kernel subsystems and may not directly affect end users unless they are using affected hardware or configurations.

Mitigation Strategies

Update the Linux kernel to a patched version that resolves CVE-2026-97914. Check your distribution's security advisories for the specific kernel version addressing this issue.
