CVE-2020-29373
Publication date 28 November 2020
Last updated 20 November 2024
Ubuntu priority
An issue was discovered in fs/io_uring.c in the Linux kernel before 5.6. It unsafely handles the root directory during path lookups, and thus a process inside a mount namespace can escape to unintended filesystem locations, aka CID-ff002b30181d.
