First I've heard about it there being a CVE for that bug. Since when
has it been considered best practice to publish CVEs without first
(or ever) directly contacting the relevant upstream developers?

But, regardless of how broken I think the CVE process is, commit
071c529 ("xfs: underflow bug in xfs_attrlist_by_handle()") should be
picked up by the stable kernels.

Cheers,

Dave.
