However, the error path labels are out of order\nrelative to the registration sequence.\n\nSpecifically:\n1. If asus_wmi_custom_fan_curve_init() fails, the driver jumps to\n   fail_custom_fan_curve. Because this label is placed below fail_sysfs,\n   it bypasses the cleanup calls for the input device and sysfs groups,\n   which were successfully registered before, leaking those resources.\n2. If asus_screenpad_init() fails, the driver jumps to fail_screenpad.\n   Because fail_screenpad is placed below fail_backlight, it bypasses the\n   cleanup calls for backlight and rfkill, leaking those resources.\n\nFix these resource leaks by reordering the error path labels in\nasus_wmi_add() to match the exact reverse order of the resource\nallocations.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10 · no fix planned: Red Hat Enterprise Linux 10 · updated 2026-09-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-93116.json)","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":38.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":207379,"id":"CVE-2026-93116","ts":1789757342026,"field":"cvss","old":null,"new":"7"},{"seq":207378,"id":"CVE-2026-93116","ts":1789757342026,"field":"severity","old":"none","new":"high"}]}
