Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: xfs: don't spin forever on zero-length dirents when salvaging them LOLLM noticed that xrep_dir_recover_data can spin forever if it encounters an unused dirent that claims to have length zero. Fix that, and prevent the same thing from happening with a zero-length entry.
