Description

In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device. A double-free flaw was found in the Linux kernel when the MPLS implementation handled sysctl allocation failures. This issue could allow a local user to cause a denial of service or possibly execute arbitrary code.
