This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

i40e: Do not use WQ_MEM_RECLAIM flag for workqueue

Issue reported by customer during SRIOV testing, call trace:

When both i40e and the i40iw driver are loaded, a warning

in check_flush_dependency is being triggered. This seems

to be because of the i40e driver workqueue is allocated with

the WQ_MEM_RECLAIM flag, and the i40iw one is not.

Similar error was encountered on ice too and it was fixed by

removing the flag. Do the same for i40e too.
