CVE: CVE-2024-53100
Published: 2024-11-25
Description: In the Linux kernel, the following vulnerability has been resolved:

nvme: tcp: avoid race between queue_lock lock and destroy

Commit 76d54bf20cdc ("nvme-tcp: don't access released socket during
error recovery") added a mutex_lock() call for the queue->queue_lock
in nvme_tcp_get_address(). However, the mutex_lock() races with
mutex_destroy() in nvme_tcp_free_queue(), and causes the WARN below.
