If ish_probe() fails, the devm-managed device resources\nincluding ishtp_dev are freed, but the work is not cancelled, causing a\nuse-after-free when the work function tries to access ishtp_dev. Use\ndevm_work_autocancel() instead, so that the work is automatically\ncancelled if probe fails.\n\n## Affected\n\n- `linux_kernel >= 4.9, < 5.15.105`\n- `linux_kernel >= 5.16, < 6.1.22`\n- `linux_kernel >= 6.2, < 6.2.9`\n- `linux_kernel = 6.3`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.2.9`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
