Description
A vulnerability in the Btrfs file system in the Linux Kernel was fixed to address a memory leak issue. When disabling quotas, if an error occurred during quota tree cleanup or root deletion, the code failed to release the reference to the quota root node, leading to a resource leak. The fix involved adding a btrfs_put_root() call in the error handling path to ensure proper reference counting and prevent memory leaks. This problem has been present since quota groups were introduced in 2012 but was only addressed recently.
