CVE-2023-53025

An expired pointer dereference flaw was found in the NFSv4 implementation in the Linux kernel, which may negatively affect system availability when the kernel thread is signaled during a mount/unmount operation.

If signal_pending() returns true, schedule_timeout() will not be executed, causing the waiting task to remain in the wait queue, which may lead to a use after free later on. This can impact system stability, leading to memory corruption and possibly arbitrary code execution.
