CVE-2024-35910 is a use-after-free condition in the Linux kernel TCP subsystem affecting transmission-timer cleanup for kernel sockets during network-namespace teardown. TCP socket closure used non-synchronous timer deletion, permitting an already executing or pending timer callback to complete after the associated network namespace had been dismantled. Unlike user sockets, kernel sockets do not retain a reference to their network namespace. The upstream fix adds synchronous TCP transmit-timer cleanup for kernel sockets, ensuring timers have terminated before the socket is released, and adds lock-ownership validation because synchronous timer cancellation must not execute while the socket lock is held.
