The channel would be removed from the list in short period of time\nbut be a bit more straight-forward here and just check for NULL instead of\nchanging the order of function calls.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE static\nanalysis tool.\n\n## Affected\n\n- `linux_kernel >= 5.4.287, < 5.4.291`\n- `linux_kernel >= 5.10.231, < 5.10.235`\n- `linux_kernel >= 5.15.174, < 5.15.179`\n- `linux_kernel >= 6.1.120, < 6.1.129`\n- `linux_kernel >= 6.6.66, < 6.6.78`\n- `linux_kernel >= 6.12.5, < 6.12.14`\n- `linux_kernel >= 6.13, < 6.13.3`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.13.3`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
