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

Description A race condition issue has been identified in the Linux kernel, specifically in the IB/rdmavt module. The problem arises from a call to the rvt error qp function without proper locking, as required by the function's documentation. This can lead to a lockdep assertion failure and potentially cause a race condition. The issue is related to the rvt ruc loopback function, where the call to rvt error qp is no longer protected by the r lock.

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