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-2026-74631

A flaw was found in the Linux kernel's smcrxsplice function within the net: smc component. This vulnerability arises from an imbalance in the lifetime management of splice entries, where page references are not properly handled before being passed to splicetopipe. This can lead to a reference cou...
