Overview

CVE-2022-49606 is a medium-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix sleep from invalid context BUG

Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a

kernel splat.

Fix this by removing the handling for RoCEv2 in

irdma_cm_teardown_connections that uses the mutex. This handling is only

needed for iWARP to avoid having connections established while the link is

down or having connections remain functional after the IP address is

removed.

BUG: sleeping function called from invalid context at kernel/locking/mutex.
