Wow, all that long article and no mention of the versions affected. Fortunately it is mentioned in the redhat bugzilla for that CVE and there it states that it is fixed in stable kernel v5.16.6. I assume it is also fixed in stable stable kernels released at the same time: 5.15.20, 5.10.97, and 5.4.177 sources: https://bugzilla.redhat.com/show_bug.cgi?id=2051505 https://bugzilla.redhat.com/show_bug.cgi?id=2051505 https://lwn.net/Articles/883949/ https://lwn.net/Articles/883949/
