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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
