Both go on to\nsnd_soc_enum_item_to_val(), which indexes e->values with no bound of\nits own, so an enum with a value table reads one element past the end.\n\nThe indexing arrived with the MUX consolidation, which relaxed the\nitem[1] check in the same hunk. The value MUX handler it deleted used\n>= there, and the snd_soc_put_enum_double() in soc-ops.c still does.\n\nOnly adav80x pairs a value table with two shifts, and its second\nchannel looks accidental, but the control does report two values.\nWriting three into it reads off the end of adav80x_mux_values. The\ncore catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which\ndefaults off.","state":0,"publishedAt":"2026-09-17T16:05:50.251+00:00","modifiedAt":"2026-10-19T08:57:25.478+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/soc/soc-dapm.c\"\n ],\n \"versions\": [\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"57ab955bde747327fb2042516ae1b7192c30e881\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"806fa4e1f2bf73c54bc4b6360790ecc69d095ca5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"496081b4edc1f6e662418831c5b14cddd8d7920c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"faf539af1a595a26e5a081a4e512caee2bc2f4c5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"32fc048391112559c34cb88d13594546939a4cd6\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"10a36512c21f861a03fba461a7ead09023df9c1b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"55126ef66298e43c69f192acebae8c7cc0022cf6\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3727b4968453dbab8fe18f979d67285eb6b66801\",\n \"lessThan\": \"14511c9b54ceeeef487409d73947c89ee8563590\",\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 \"sound/soc/soc-dapm.c\"\n ],\n \"versions\": [\n {\n \"version\": \"3.15\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"3.15\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.270\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.221\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.188\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.157\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.110\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.52\",\n \"lessThanOrEqual\": \"6.18.*\",\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/57ab955bde747327fb2042516ae1b7192c30e881","https://git.kernel.org/stable/c/806fa4e1f2bf73c54bc4b6360790ecc69d095ca5","https://git.kernel.org/stable/c/496081b4edc1f6e662418831c5b14cddd8d7920c","https://git.kernel.org/stable/c/faf539af1a595a26e5a081a4e512caee2bc2f4c5","https://git.kernel.org/stable/c/32fc048391112559c34cb88d13594546939a4cd6","https://git.kernel.org/stable/c/10a36512c21f861a03fba461a7ead09023df9c1b","https://git.kernel.org/stable/c/55126ef66298e43c69f192acebae8c7cc0022cf6","https://git.kernel.org/stable/c/14511c9b54ceeeef487409d73947c89ee8563590"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90068","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90068","identifiers":["CVE-2026-90068"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
