CVE-2022-3625: Linux Kernel IPsec devlink.c devlink_param_get use after free

First published: Tue Aug 09 2022(Updated: )

A flaw was found in the Netlink device interface implementation in the Linux kernel that improperly handled certain error conditions, leading to a use-after-free issue with some network device drivers. A local attacker with admin access to the network device could use this to cause a denial of service (system crash) or execute arbitrary code.
