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.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
