kernel: tcp: properly terminate timers for kernel sockets

A flaw was found in the Linux kernel's TCP subsystem. When kernel-managed TCP sockets are closed, active network timers may continue executing after the associated network namespace has been dismantled and freed. A local attacker can exploit this timing condition to trigger a use-after-free memor...
