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

Description: The issue is related to a NULL pointer dereference in the IB/hfi1 component of the Linux kernel. An early failure in hfi1 ipoib setup rn() can lead to a panic due to a NULL dereference when hfi1 ipoib netdev dtor() is called. The functions hfi1 ipoib txreq init() and hfi1 ipoib rxq init() are self-unwinding, and the fix involves adjusting the error paths accordingly. Other changes include deleting hfi1 ipoib free rdma netdev() and moving the switch to accelerated entrances to the success path.

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