In the Linux kernel, the following vulnerability has been resolved:
xfrm: Fix leak of dev tracker
At the stage of direction checks, the netdev reference tracker is
already initialized, but released with wrong *_put() call.
A flaw was found in the Linux kernel. A local attacker with low privileges could exploit a resource leak vulnerability within the xfrm subsystem. This occurs because a network device (netdev) reference tracker is incorrectly released during direction checks. Successful exploitation can lead to a Denial of Service (DoS) due to the exhaustion of system resources.
