Overview
Affected versions of this package are vulnerable to Use After Free in the unix_stream_bpf_update_proto process. An attacker can cause kernel memory corruption, information disclosure, or denial of service by racing the update of a sockmap with the closure of an AF_UNIX socket, leading to access of freed memory.
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
