Description OSIDB Bzimport 2024-09-18 08:21:37 UTC

In the Linux kernel, the following vulnerability has been resolved:

btrfs: don't BUG_ON() when 0 reference count at btrfs_lookup_extent_info()

Instead of doing a BUG_ON() handle the error by returning -EUCLEAN,
aborting the transaction and logging an error message.
