Referencing the input_dev would lead to a\nuse-after-free when the input_dev was unregistered and subsequently fires a\nuevent that depends on the name. At the point of firing the uevent, the\nname would be freed by devres management.\n\nUse devm_kasprintf to simplify the logic for allocating memory and\nformatting the input_dev name string.\n\n## Affected\n\n- `linux_kernel >= 3.12, < 4.14.326`\n- `linux_kernel >= 4.15, < 4.19.295`\n- `linux_kernel >= 4.20, < 5.4.257`\n- `linux_kernel >= 5.5, < 5.10.195`\n- `linux_kernel >= 5.11, < 5.15.132`\n- `linux_kernel >= 5.16, < 6.1.53`\n- `linux_kernel >= 6.2, < 6.4.16`\n- `linux_kernel >= 6.5, < 6.5.3`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.5.3`","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
