{"id":"CVE-2026-93116","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-93116","summary":"platform/x86: asus-wmi: fix resource leaks on probe failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: asus-wmi: fix resource leaks on probe failure\n\nDuring driver initialization in asus_wmi_add(), various subsystems are\nregistered sequentially. 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.","published":"2026-09-17T16:11:23.852Z","modified":"2026-09-19T03:47:27.851678134Z","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.2.6"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3308b8c5f5a28403611a2f5a46f06aabe4f0c661"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef3daa2b84a2b8499ce9e2ce1c865dca36d39f95"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93116.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93116"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T03:47:27.851678134Z"}}
