VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.7.0
Description The vulnerability is related to a suspicious RCU usage warning in the Linux kernel. It was discovered while running cthon against an ontap server running pNFS. The warning indicates that an RCU-list was traversed in a non-reader section, which could potentially lead to a denial-of-service attack. The vulnerability is associated with the rpc xprt switch has addr function in the net/sunrpc/xprtmultipath.c file.
Recommendations To resolve the issue, update the Linux kernel to a version that includes the fix for the suspicious RCU usage warning. Specifically, versions prior to 6.7.0 are affected, so updating to 6.7.0 or later should mitigate the vulnerability.
Note: The provided information does not specify the exact version that includes the fix, but it is mentioned that the issue is resolved in the Linux kernel. Therefore, updating to the latest available version is recommended.
