{"id":"CVE-2026-90060","summary":"ALSA: control: Don't add invalid kcontrols to LED layer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: control: Don't add invalid kcontrols to LED layer\n\nThe kcontrol LED state layer tries to track the all associated\nkcontrol elements with naive assumptions that they are readable.\nBut one can create a write-only element that has no get callback (even\na user element can do it), and this may lead to a NULL dereference at\nthe call chain of snd_ctl_led_notify(), as found by syzkaller.\n\nFor avoiding the Oops, add a sanity check of the kcontrol's info and\nget callbacks, and just skip the invalid kcontrols before assigning\nthe kctl to the LED layer.","modified":"2026-09-18T03:48:35.470859182Z","published":"2026-09-17T16:05:44.515Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90060.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/18c08f84ca483029f04e426ec7ca3b5d3684cf22"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f0c97b1a32fba8e81a69f6231aa0b3c9b6bc581"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3d20cd049fc5f51f80e24a2db7a3cf00593c79e4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6e152cbfac3a2a62f79df7d23d621917c20367eb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74e3b979ce8b78a690f8b94ccf2e2c965f7f5c11"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90060.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90060"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"22d8de62f11b287b279f1d4473a78c7d5e53e7bc"},{"fixed":"6e152cbfac3a2a62f79df7d23d621917c20367eb"},{"fixed":"3d20cd049fc5f51f80e24a2db7a3cf00593c79e4"},{"fixed":"2f0c97b1a32fba8e81a69f6231aa0b3c9b6bc581"},{"fixed":"18c08f84ca483029f04e426ec7ca3b5d3684cf22"},{"fixed":"74e3b979ce8b78a690f8b94ccf2e2c965f7f5c11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90060.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.13.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"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-2026-90060.json"}}],"schema_version":"1.9.0"}
