Kerentanan NULL Pointer Dereference pada zephyrproject zephyr. Skor CVSS 3.1 5.3 (Medium) menurut NVD.

Deskripsi (NVD)

A race condition during TCP connection teardown can cause tcp_recv() to operate on a connection that has already been released. If tcp_conn_search() returns NULL while processing a SYN packet, a NULL pointer derived from stale context data is passed to tcp_backlog_is_full() and dereferenced without validation, leading to a crash.
