CVE-2022-50293 btrfs: do not BUG_ON() on ENOMEM when dropping extent items for a range

In the Linux kernel, the following vulnerability has been resolved: btrfs: do not BUGON on ENOMEM when dropping extent items for a range If we get -ENOMEM while dropping file extent items in a given range, at btrfsdropextents, due to failure to allocate memory when attempting to increment the...

CVE-2022-50293

CVE-2022-50293 affects the Linux kernel btrfs subsystem. When dropping file extent items for a range, ENOMEM could trigger a BUG_ON() path in btrfs_drop_extents(); the fix replaces those BUG_ON()s with proper transaction abort and error return handling. This means that instead of halting the tran...
