Tested it with another driver (ax88179_178a), since\nI don't have a aqc111 device to test it, but the code looks very similar.\n\n## Affected\n\n- `linux_kernel >= 5.0, < 5.4.190`\n- `linux_kernel >= 5.5, < 5.10.112`\n- `linux_kernel >= 5.11, < 5.15.35`\n- `linux_kernel >= 5.16, < 5.17.4`\n- `linux_kernel = 5.18`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 5.17.4`","depth":"sunlit","depthScore":37,"depthScoreParts":{"impact":37.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
