CVE-2022-36879

Published: 27 July 2022

An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice.

From the Ubuntu Security Team

It was discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel contained a reference counting error. A local attacker could use this to cause a denial of service (system crash).
