| Vector | AV:L/AC:H/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s nvme-fc module related to accessing port and remote port states without proper locking mechanisms. Specifically, the
nvme fc unregister remote function can remove a remote port while the reconnect logic is attempting to access the same port state without a lock, leading to a race condition. This occurs because nvme fc create association does not acquire a lock to verify the port state and increment the active count on the remote port.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
