CVE-2023-1611: Use After Free
First published: Thu Mar 23 2023(Updated: )
A slab-use-after-free read flaw was found in btrfs_search_slot in fs/btrfs/ctree.c The quota assigned ioctl can currently run in parallel with a quota disable ioctl call. The assign ioctl uses the quota root, while the disable ioctl frees that root, and therefore we can have a use-after-free triggered in the assign ioctl.
