Generally, kthread_stop() is called\nfirst, and in this case, no particular issues occur.\n\nHowever, in rare instances where kthread_complete_and_exit() is called\nfirst and then kthread_stop() is called, a UAF occurs because the kthread\nobject, which has already exited and been freed, is accessed again.\n\nTherefore, to prevent this with minimal modification, you must remove\nkthread_stop() and change the code to wait until the self-exit operation\nis completed.\n\n## Affected\n\n- `linux_kernel >= 3.18.139, < 3.19`\n- `linux_kernel >= 4.4.179, < 4.5`\n- `linux_kernel >= 4.9.170, < 4.10`\n- `linux_kernel >= 4.14.113, < 4.15`\n- `linux_kernel >= 4.19.36, < 5.10.258`\n- `linux_kernel >= 5.11, < 5.15.209`\n- `linux_kernel >= 5.16, < 6.1.175`\n- `linux_kernel >= 6.2, < 6.6.140`\n- `linux_kernel >= 6.7, < 6.12.88`\n- `linux_kernel >= 6.13, < 6.18.30`\n- `linux_kernel >= 6.19, < 7.0.7`\n- `linux_kernel = 7.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 7.0.7`","depth":"sunlit","depthScore":26,"depthScoreParts":{"impact":25.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
