Overview
Affected versions of this package are vulnerable to Use After Free through the siw_query_port process. An attacker can cause kernel memory corruption and potentially execute arbitrary code or crash the system by racing the teardown of a network device with repeated queries, leading to dereferencing of a freed pointer. This is only exploitable if an attacker has the ability to trigger both network device teardown and repeated port queries within a network namespace.
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
