CVE-2023-53781

CVE-2023-53781 affects the Linux kernel: a use-after-free in tcp_write_timer_handler() can occur when SMC creates a kernel socket (__smc_create()) and the socket is freed without stopping TCP timers if the parent SMC socket’s sk_state isn’t TCP_CLOSE. The issue arises because inet_csk_destroy_soc...
