Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-14 18:31

Details

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

btrfs: fix possible memory leak in btrfs_get_dev_args_from_path()

In btrfs_get_dev_args_from_path(), btrfs_get_bdev_and_sb() can fail if the path is invalid. In this case, btrfs_get_dev_args_from_path() returns directly without freeing args->uuid and args->fsid allocated before, which causes memory leak.

To fix these possible leaks, when btrfs_get_bdev_and_sb() fails, btrfs_put_dev_args_from_path() is called to clean up the memory.

Severity

5.5 (Medium)
