CVE-2019-19816

Publication date 17 December 2019

Last updated 9 October 2024


Ubuntu priority

Cvss 3 Severity Score

7.8 · High

Score breakdown

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image and performing some operations can cause slab-out-of-bounds write access in __btrfs_map_block in fs/btrfs/volumes.c, because a value of 1 for the number of data stripes is mishandled.

From the Ubuntu Security Team

It was discovered that the btrfs file system implementation in the Linux kernel did not properly validate file system metadata in some situations. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service (system crash).
