Due to the lack\nof the info, it caused a kernel crash on hw20k2, which was already\nworked around by the commit b045ab3dff97 (\"ALSA: ctxfi: Fix missing\nSPDIFI1 index handling\").\n\nThis patch addresses the root cause of the regression above properly,\nsimply by skipping the incorrect SPDIF1 type in the parser loop.\n\nFor making the change clearer, the code is slightly arranged, too.","state":0,"publishedAt":"2026-05-01T14:15:03.664+00:00","modifiedAt":"2026-10-26T15:12:57+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                        \"sound/pci/ctxfi/ctatc.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"88cc09bb70651917ef8b7095a05a21a9ca014c94\",\n                            \"lessThan\": \"7fca3600e79e9f8bac1ebc10af9ff20a35d6cccb\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"a2dbaeb5c61ef110ceefe0d48fe94d428d3bcf16\",\n                            \"lessThan\": \"a79c4c42057818bd9de45d2627464b4f0e02196a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"a2dbaeb5c61ef110ceefe0d48fe94d428d3bcf16\",\n                            \"lessThan\": \"75dc1980cf48826287e43dc7a49e310c6691f97e\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6.18.57\",\n                            \"lessThan\": \"6.18.59\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\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                        \"sound/pci/ctxfi/ctatc.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.59\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.19.12\",\n                            \"lessThanOrEqual\": \"6.19.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.0\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/7fca3600e79e9f8bac1ebc10af9ff20a35d6cccb","https://git.kernel.org/stable/c/a79c4c42057818bd9de45d2627464b4f0e02196a","https://git.kernel.org/stable/c/75dc1980cf48826287e43dc7a49e310c6691f97e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-31775","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-31775","identifiers":["CVE-2026-31775"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
