{"id":"CVE-2026-93128","summary":"platform/x86: lg-laptop: Fix LED resource handling","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: lg-laptop: Fix LED resource handling\n\nThe event notification callback might access kbd_backlight even\nwhen it was not successfully registered with the LED subsystem.\nThe same happens inside acpi_remove(), where the LED devices are\nunregistered unconditionally.\n\nFix this by tracking the availability of the kbd_backlight LED\ndevice and use devm_led_classdev_register() to let devres take\ncare of unregistering the LED devices during removal. For this\nthe parent device of the LED devices is changed to the native\nplatform device.","modified":"2026-09-18T03:48:44.550983997Z","published":"2026-09-17T16:11:31.933Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93128.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3e91964aa74ab261aa15d9d96318eded2fd9d22a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4fbfe3714f645b6c64c9ba8faa83b27e4c9f2edd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9a85e2d35e54248aca39bad4f4152ed34de1995f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/acc190322250562d5f28860f4ae1ebaf3e304fc2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93128.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93128"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ae26278829a80ad0e60ff004de71e9276cee5dc0"},{"fixed":"4fbfe3714f645b6c64c9ba8faa83b27e4c9f2edd"},{"fixed":"9a85e2d35e54248aca39bad4f4152ed34de1995f"},{"fixed":"acc190322250562d5f28860f4ae1ebaf3e304fc2"},{"fixed":"3e91964aa74ab261aa15d9d96318eded2fd9d22a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93128.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93128.json"}}],"schema_version":"1.9.0"}
