This was harmless while the drivers\nwere built-in, but now that they can be built as modules and\nunbound/rmmod'd it leaves behind a dangling IRQ domain, interrupt mappings\nwhose chip data points at freed memory, and a chained handler that keeps\nfiring into that freed data.\n\nThe plain allocations in mtk_eint_do_init() already use the device-managed\ndevm_*() helpers, so tear the remaining resources down the same way:\nregister a devm action that detaches the chained handler, waits for any\nin-flight handler to finish, disposes of the per-line mappings and removes\nthe IRQ domain. This mirrors the device-managed lifecycle adopted for the\nGPIO chip and keeps the whole EINT setup self-cleaning on unbind.","state":0,"publishedAt":"2026-09-17T16:09:58.378+00:00","modifiedAt":"2026-10-19T09:03:47.42+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 \"drivers/pinctrl/mediatek/mtk-eint.c\"\n ],\n \"versions\": [\n {\n \"version\": \"e46df235b4e605aa4e7609a27c118a1cccd4ff9a\",\n \"lessThan\": \"23252bc1cd9a58a039c9b1ae77b22d2b33da48e9\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e46df235b4e605aa4e7609a27c118a1cccd4ff9a\",\n \"lessThan\": \"903a7cdf63a81d3738594c5bd1b5955f58fda427\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e46df235b4e605aa4e7609a27c118a1cccd4ff9a\",\n \"lessThan\": \"51552c8c60d3b1fecc062eab2d8cfeaa1cb339dd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e46df235b4e605aa4e7609a27c118a1cccd4ff9a\",\n \"lessThan\": \"7f6d898179ca4771ee602bdad4246c3952af83eb\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e46df235b4e605aa4e7609a27c118a1cccd4ff9a\",\n \"lessThan\": \"e06785cba7f86d72abd531058b1a82d6952a7346\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e46df235b4e605aa4e7609a27c118a1cccd4ff9a\",\n \"lessThan\": \"88292b7103d260e3e606eb3bb2794060a5fde48e\",\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 \"drivers/pinctrl/mediatek/mtk-eint.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.18\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.18\",\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/23252bc1cd9a58a039c9b1ae77b22d2b33da48e9","https://git.kernel.org/stable/c/903a7cdf63a81d3738594c5bd1b5955f58fda427","https://git.kernel.org/stable/c/51552c8c60d3b1fecc062eab2d8cfeaa1cb339dd","https://git.kernel.org/stable/c/7f6d898179ca4771ee602bdad4246c3952af83eb","https://git.kernel.org/stable/c/e06785cba7f86d72abd531058b1a82d6952a7346","https://git.kernel.org/stable/c/88292b7103d260e3e606eb3bb2794060a5fde48e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92481","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92481","identifiers":["CVE-2026-92481"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
