kernel: udp: Fix memory accounting leak.

A memory overflow vulnerability exists within the Linux kernel's networking subsystem. Specifically, an application can set the SORCVBUF socket option to its maximum value INTMAX, which triggers an integer overflow within the udprmemrelease function during socket closure. The udpdestructcommon...
