Technical Description

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix f2fs_bug_on when uninstalling filesystem call f2fs_evict_inode.

creating a large files during checkpoint disable until it runs out of

space and then delete it, then remount to enable checkpoint again, and

then unmount the filesystem triggers the f2fs_bug_on as below:
