CVE-2019-19377 in Ubuntu

CVE-2019-19377

Priority

Description

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image,
performing some operations, and unmounting can lead to a use-after-free in
btrfs_queue_work in fs/btrfs/async-thread.c.

Ubuntu-Description

It was discovered that the btrfs implementation in the Linux kernel did not
properly detect that a block was marked dirty in some situations. An
attacker could use this to specially craft a file system image that, when
unmounted, could cause a denial of service (system crash).
