here udev->dev.power.runtime_status == RPM_SUSPENDING\n aqc111_suspend() - called for the usb device interface\n aqc111_write32_cmd()\n usb_autopm_get_interface()\n pm_runtime_resume_and_get()\n rpm_resume() - here we call rpm_resume() on our parent\n rpm_resume() - Here we wait for a status change that will never happen.\n\nAt this point we block another task which holds\nrtnl_lock and locks up the whole networking stack.\n\nFix this by replacing the write_cmd calls with their _nopm variants","state":0,"publishedAt":"2026-04-03T15:15:29.863+00:00","modifiedAt":"2026-10-15T01:15:07.658+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/net/usb/aqc111.c\"\n ],\n \"versions\": [\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"cc06ac99fd78839b2d38850785731ef131d9ae26\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"b87f361d41f9a7f1f6c426947ca815651c481376\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"621f2f43741b51f62d767eb4752fbcefe2526926\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"4de6a43e8ecf961feabddf0e9d6911081d2ed218\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"3267bcb744ee8a2feabaa7ab69473f086f67fd71\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"d3e32a612c6391ca9b7c183aeec22b4fd24c300c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"98e8aed64614b0c199d5f0391fbe1a4331cb5773\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc\",\n \"lessThan\": \"069c8f5aebe4d5224cf62acc7d4b3486091c658a\",\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/net/usb/aqc111.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.0\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.0\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.253\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.203\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.167\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.130\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.78\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.20\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.19.10\",\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/cc06ac99fd78839b2d38850785731ef131d9ae26","https://git.kernel.org/stable/c/b87f361d41f9a7f1f6c426947ca815651c481376","https://git.kernel.org/stable/c/621f2f43741b51f62d767eb4752fbcefe2526926","https://git.kernel.org/stable/c/4de6a43e8ecf961feabddf0e9d6911081d2ed218","https://git.kernel.org/stable/c/3267bcb744ee8a2feabaa7ab69473f086f67fd71","https://git.kernel.org/stable/c/d3e32a612c6391ca9b7c183aeec22b4fd24c300c","https://git.kernel.org/stable/c/98e8aed64614b0c199d5f0391fbe1a4331cb5773","https://git.kernel.org/stable/c/069c8f5aebe4d5224cf62acc7d4b3486091c658a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-23446","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-23446","identifiers":["CVE-2026-23446"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
