Debounce clock reference leak: The debounce clock (bank->db_clk) is\n obtained using of_clk_get() which increments the clock's reference\n count, but clk_put() is never called. Register a devm action to\n cleanly release it on unbind. Note that of_clk_get(..., 1) remains\n necessary over devm_clk_get() because the DT binding does not define\n clock-names, precluding name-based lookup.\n\n2. Unregistered chained IRQ handler: The chained IRQ handler is not\n disconnected in remove(). If a stray interrupt fires after the driver\n is removed, the kernel attempts to execute a stale handler, leading\n to a panic. Fix this by clearing the handler in remove().\n\n3. IRQ domain leak: The linear IRQ domain and its generic chips are\n allocated manually during probe but never removed. Remove the IRQ\n domain during driver teardown to free the associated generic chips\n and mappings.\n\n[Bartosz: don't emit an error message on devres allocation failure]","state":0,"publishedAt":"2026-07-24T15:27:44.144+00:00","modifiedAt":"2026-10-21T12:43:12.33+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/gpio/gpio-rockchip.c\"\n ],\n \"versions\": [\n {\n \"version\": \"936ee2675eee1faca0dcdfa79165c7990422e0fc\",\n \"lessThan\": \"77b6ff33c8f5642f7e7c1ca691857218683264fd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"936ee2675eee1faca0dcdfa79165c7990422e0fc\",\n \"lessThan\": \"cdc603ce3118232712ba443dd8b414d8f25ca467\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"936ee2675eee1faca0dcdfa79165c7990422e0fc\",\n \"lessThan\": \"7f945f7f10f442270518dfd768d230227c495fcf\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"936ee2675eee1faca0dcdfa79165c7990422e0fc\",\n \"lessThan\": \"6be81e77e1748665d7ddab9128ff1d35eb75b87d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"936ee2675eee1faca0dcdfa79165c7990422e0fc\",\n \"lessThan\": \"9500077678230e36d22bf16d2b9539c13e59a801\",\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/gpio/gpio-rockchip.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.15\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.15\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.160\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.96\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.35\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.0.12\",\n \"lessThanOrEqual\": \"7.0.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/77b6ff33c8f5642f7e7c1ca691857218683264fd","https://git.kernel.org/stable/c/cdc603ce3118232712ba443dd8b414d8f25ca467","https://git.kernel.org/stable/c/7f945f7f10f442270518dfd768d230227c495fcf","https://git.kernel.org/stable/c/6be81e77e1748665d7ddab9128ff1d35eb75b87d","https://git.kernel.org/stable/c/9500077678230e36d22bf16d2b9539c13e59a801"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-64241","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-64241","identifiers":["CVE-2026-64241"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
