CVE-2025-22062
CVE-2025-22062 is a Linux kernel vulnerability where mutual exclusion was missing in proc_sctp_do_udp_port(), risking a crash due to unsynchronized calls to sctp_udp_sock_stop() and sctp_udp_sock_start(). The issue is evidenced by syzbot exposé showing a crash/OOPS from a non-canonical address. T...
