Worse, when the\ndriver is force-bound to a device without an ACPI companion, probe\nstill succeeds and stores a NULL companion pointer, which\nasus_wireless_remove() later passes to acpi_dev_remove_notify_handler(),\nleading to a NULL pointer dereference on unbind.\n\nReturn -ENODEV when the device does not match the ID table.  This also\ncovers the missing-companion case, because acpi_match_acpi_device()\nrejects a NULL device.  Perform the check before allocating any driver\nstate, instead of after the input device has already been registered.","state":0,"publishedAt":"2026-09-17T16:11:29.223+00:00","modifiedAt":"2026-10-19T09:05:57.673+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/platform/x86/asus-wireless.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"f7e648027d7e1b5c06eb86d944b7e23926254cee\",\n                            \"lessThan\": \"7bfa711f311a584002e16ecd750627306deb805c\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"f7e648027d7e1b5c06eb86d944b7e23926254cee\",\n                            \"lessThan\": \"4aefd66ef7822cf7d3f53146dcee0b71021ed2b7\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/platform/x86/asus-wireless.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/7bfa711f311a584002e16ecd750627306deb805c","https://git.kernel.org/stable/c/4aefd66ef7822cf7d3f53146dcee0b71021ed2b7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93124","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93124","identifiers":["CVE-2026-93124"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
