Kernel: btrfs: double free in btrfs_get_root_ref()

Published: 8/16/2023 Last updated: 10/15/2024 Reserved: 8/16/2023

A flaw was found in btrfs_get_root_ref in fs/btrfs/disk-io.c in the btrfs filesystem in the Linux Kernel due to a double decrement of the reference count. This issue may allow a local attacker with user privilege to crash the system or may lead to leaked internal kernel information.
