[SRU OEM-5.17, OEM-6.0 0/1] CVE-2023-26545

[Cengiz Can]

[Impact]
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.

[Fix]
Cherry picked from upstream.

[Test case]
Compile and boot tested only.

[Potential regression]
Low. Fix only adds a null check to prevent a double free.
