Doc Text:	A flaw was found in the Linux kernel's Arm Ethos-U accelerator driver. When scheduler initialization fails during a job open operation, the driver returns an incorrect positive status code instead of a standard negative error number. A local user can trigger this issue by opening an accelerator job file descriptor, which may cause user-space applications to improperly handle initialization failures and lead to unexpected behavior.

Description OSIDB Bzimport 2026-09-25 10:49:17 UTC

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()).
