CVE-2026-68334

A flaw was found in the Linux kernel's rxrpc component. A race condition in the rxrpcwakeupiothread function could lead to a null pointer dereference. This occurs when the iothread pointer is checked and then reloaded, and if the I/O thread exits between these operations, the second load can resu...
