CVE-2026-74692

A flaw was found in the Linux kernel's net/smc component. A time-of-check to time-of-use TOCTOU race condition allows a remote attacker to exploit a window where the listener's state is checked without proper locking. By opening TCP connections while the server is closing, an attacker can cause a...

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() ...
