Return the error when the widget is not\nset to avoid a null pointer dereference like below when the topology is\nbroken.\n\nRIP: 0010:hda_dai_get_ops.isra.0+0x14/0xa0 [snd_sof_intel_hda_common]","modified":"2026-06-18T03:55:01.139720547Z","published":"2026-05-06T11:27:23.592Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43137.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/10411f1f2c76be67103b1f95822ff629aa25e2aa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/16c589567a956d46a7c1363af3f64de3d420af20"},{"type":"WEB","url":"https://git.kernel.org/stable/c/42068f7dd42b559c4eeae645e1455ff36518866a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7750d78b4014902bc0ac03d4bb30faa076a913ab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a1d4f3d3c0dc86527da6a19f6901a6a48375500d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43137.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43137"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0acb48dd31e39b617bb12ca546b4fecd6ccb2972"},{"fixed":"a1d4f3d3c0dc86527da6a19f6901a6a48375500d"},{"fixed":"10411f1f2c76be67103b1f95822ff629aa25e2aa"},{"fixed":"42068f7dd42b559c4eeae645e1455ff36518866a"},{"fixed":"7750d78b4014902bc0ac03d4bb30faa076a913ab"},{"fixed":"16c589567a956d46a7c1363af3f64de3d420af20"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43137.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43137.json"}}],"schema_version":"1.7.5"}
