Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw in the btrfs subsystem where a BUG ON() call occurs on ENOMEM when dropping extent items for a range. This can happen due to memory allocation failures when incrementing or dropping reference counts for extents. The issue is resolved by replacing the BUG ON() calls with logic to abort the transaction and return the error to the caller. This ensures proper error handling and prevents unexpected system behavior.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
