Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the __xfrm_policy_check process. An attacker can cause a kernel crash and system denial of service by sending specially crafted network packets that trigger a race condition during IPsec Security Association teardown, leading to a NULL pointer dereference in kernel space.
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
