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

jfs: nlink overflow in jfs_rename

If nlink is maximal for a directory (-1) and inside that directory you

perform a rename for some child directory (not moving from the parent),

then the nlink of the first directory is first incremented and later

decremented. Normally this is fine, but when nlink = -1 this causes a

wrap around to 0, and then drop_nlink issues a warning.

After applying the patch syzbot no longer issues any warnings. I also

ran some basic fs tests to look for any regressions. (NVD)
