CVE-2026-74692

A TOCTOU race condition in the Linux kernel's net/smc module allows a remote attacker to trigger kernel memory exhaustion. The function smc_listen_out() reads the listener's socket state without holding the listener lock, then acquires the lock only afterward. This window lets smc_close_active() ...
