Description OSIDB Bzimport 2024-09-18 08:21:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

btrfs: replace BUG_ON() with error handling at update_ref_for_cow()

Instead of a BUG_ON() just return an error, log an error message and
abort the transaction in case we find an extent buffer belonging to the
relocation tree that doesn't have the full backref flag set. This is
unexpected and should never happen (save for bugs or a potential bad
memory).
