Overview

Affected versions of this package are vulnerable to Use After Free through a race condition in the dev3_register_work process. An attacker can achieve arbitrary code execution, kernel memory disclosure, and system instability by exploiting the delayed work item after the associated memory has been freed. This is only exploitable if a local user has access to device files and can emulate a SERIO_8042 ALPS device, inject packets, and provoke teardown.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
