Technical details
The vulnerability exists in the open-source kernel module's event delivery path, where a race condition between asynchronous event delivery and file close operations can lead to a use-after-free condition. An unprivileged local attacker can trigger this race without elevated privileges, and exploitation may result in kernel code execution, privilege escalation, denial of service, information disclosure, or data tampering depending on attack success.
