After catching site of a story on SANS – see this link – and reading the linked articles, I could not tell if kernel version 18.104.22.168 was vulnerable or not – the wording is a little ambiguous. Reading the changelog for 22.214.171.124 indicated a fix for a pointer issue, which *looks* related to the problem affecting all kernels prior to (and possibly including, I cannot tell) 126.96.36.199. I am tired and not too bright today, so I just gave in and updated to 188.8.131.52 as a “just in case”.
Of course, this means reinstalling the nvidia driver and reapplying vmware-any-any-update115a. Oh well.
Update: Tag Surfer fed this blog up on the same thing.
