The product does not lock or does not correctly lock a resource when the product must have exclusive access to the resource.
An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-413: Improper Resource Locking. The product does not lock or does not correctly lock a resource when the product must have exclusive access to the resource.
