Ubuntu.comUB:CVE-2021-47184CVE-2021-47184
In the Linux kernel, the following vulnerability has been resolved: i40e:
Fix NULL ptr dereference on VSI filter sync Remove the reason of null
pointer dereference in sync VSI filters. Added new I40E_VSI_RELEASING flag
to signalize deleting and releasing of VSI resources to sync this thread
with sync filters subtask. Without this patch it is possible to start
update the VSI filter list after VSI is removed, that’s causing a kernel
oops.
