CVE-2024-49867 is a use-after-free vulnerability in the Linux kernel's Btrfs filesystem during unmount operations. The issue arises because the kernel does not wait for fixup worker threads to complete before stopping and freeing the cleaner kernel thread, leading to potential crashes. This flaw was reported by syzbot and results in kernel crashes due to accessing freed memory. The vulnerability has been fixed by ensuring the kernel waits for fixup workers before stopping the cleaner thread.
