CVE-2026-99067

btrfs: scrub: fix local_root reference leak in scrub_print_warning_inode()

State: Published
Severity: Not scored
Published: Oct 23, 2026
Updated: Oct 30, 2026
Reserved: Sep 25, 2026

Description

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

btrfs: scrub: fix local_root reference leak in scrub_print_warning_inode()

When paths_from_inode() fails, scrub_print_warning_inode() jumps to err without dropping the reference taken by btrfs_get_fs_root(), leaking a reference to the root every time path resolution fails while printing scrub warnings. Every other error and success path of the function drops the reference.

Drop the reference on the paths_from_inode() failure path too.
