Race Condition Affecting kernel-abi-stablelists package, versions <0:4.18.0-553.16.1.el8_10

Note: Versions mentioned in the description apply only to the upstream kernel-abi-stablelists package and not the kernel-abi-stablelists package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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

i40e: fix vf may be used uninitialized in this function warning

To fix the regression introduced by commit 52424f974bc5, which causes servers hang in very hard to reproduce conditions with resets races. Using two sources for the information is the root cause. In this function before the fix bumping v didn't mean bumping vf pointer. But the code used this variables interchangeably, so stale vf could point to different/not intended vf.

Remove redundant "v" variable and iterate via single VF pointer across whole function instead to guarantee VF pointer validity.
