Vulnerability from fkie_nvd - Published: 2026-05-06 12:16 - Updated: 2026-05-13 21:03

Severity ?

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

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.

Normally this is fine, but when nlink = -1 this causes a\nwrap around to 0, and then drop_nlink issues a warning.\n\nAfter applying the patch syzbot no longer issues any warnings.
