A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A fix is available and has been committed to the Linux kernel source. Users and administrators should update to the fixed kernel version or apply the relevant patches to ensure correct error handling in the ethosu driver. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's accel ethosu component related to the ethosu_job_open() function return value has been fixed. The issue involved a WARN_ON() macro returning 0 or 1 instead of the original negative errno, potentially causing incorrect error reporting. The fix removes the WARN_ON() to allow the file descriptor open operation to correctly pass the error code to userspace.

Impact

The vulnerability could cause incorrect error reporting to userspace when opening a file descriptor in the ethosu driver, potentially leading to improper handling of error conditions by applications relying on this interface. There is no indication of direct exploitation or broader security impact beyond error code misreporting.

Summary

The Linux kernel's accel ethosu driver contained a flaw in the ethosu_job_open() function where WARN_ON() returned 0 or 1 instead of the original negative errno value. This could lead to improper error handling as the return code passed to userspace would not reflect the actual error from drm_sched_entity_init(). The fix involved dropping the WARN_ON() call, ensuring the correct error code is propagated to userspace. This resolves the issue in version 6.19 of the Linux kernel, with the fix committed in the referenced patches.
