Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2278267]

Comment 5 Phil Sutter 2024-06-21 16:00:13 UTC

I don't see any relation to security in the CVE fixing commit. The effect is merely for PPPoE packages to not match the flowtable entry when they should and so continue to traverse the standard forwarding path through the kernel. This is bad because flowtables are unusable with PPPoE, but it's more or less just a lack of feature. Can we at least lessen severity/priority values and perhaps also contest the CVE itself?
