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. I also\nran some basic fs tests to look for any regressions.\n\n## Affected\n\n- `linux_kernel >= 2.6.12.1, < 5.10.252`\n- `linux_kernel >= 5.11, < 5.15.202`\n- `linux_kernel >= 5.16, < 6.1.165`\n- `linux_kernel >= 6.2, < 6.6.128`\n- `linux_kernel >= 6.7, < 6.12.75`\n- `linux_kernel >= 6.13, < 6.18.16`\n- `linux_kernel >= 6.19, < 6.19.6`\n- `linux_kernel = 2.6.12`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.19.6`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
