CVE-2024-0562

HIGH

Linux Kernel >=5.15 <5.15.164 - Use-After-Free in bdi_writeback

Title source: llm
STIX 2.1

Description

A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to stop further write-back and waits for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result in the timer attempting to access the recently freed bdi_writeback.
