Overview

Affected versions of this package are vulnerable to Use After Free in the dst_release process. An attacker can corrupt kernel memory, disclose sensitive kernel heap contents, or cause a denial of service by triggering use-after-free conditions through manipulation of network namespaces and tunnel configurations. This is only exploitable if the attacker has local privileges to configure network namespaces and tunnels, and can perform namespace teardown operations.

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
