CVE-2022-49606

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A bug in the Linux kernel has been identified, specifically in the RDMA/irdma component. The issue arises when the qos mutex is taken to process RoCEv2 QP's on netdev events, resulting in a kernel splat. This occurs because the handling for RoCEv2 in irdma cm teardown connections uses the mutex, which is unnecessary for RoCEv2 and only required for iWARP. The error is indicated by a "sleeping function called from invalid context" message at kernel/locking/mutex, accompanied by a call trace.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
