Overview

Affected versions of this package are vulnerable to Use After Free in the rawsock_release process. An attacker can execute arbitrary code in kernel context or cause a denial of service by racing the execution of tx_work with socket and device teardown, leading to dereferencing freed memory through heap spraying techniques.

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
