{"id":"CVE-2026-23446","summary":"net: usb: aqc111: Do not perform PM inside suspend callback","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: usb: aqc111: Do not perform PM inside suspend callback\n\nsyzbot reports \"task hung in rpm_resume\"\n\nThis is caused by aqc111_suspend calling\nthe PM variant of its write_cmd routine.\n\nThe simplified call trace looks like this:\n\nrpm_suspend()\n  usb_suspend_both() - here udev-\u003edev.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","modified":"2026-06-04T09:14:22.334423981Z","published":"2026-04-03T15:15:29.863Z","related":["SUSE-SU-2026:21841-1","SUSE-SU-2026:21845-1","SUSE-SU-2026:21860-1","SUSE-SU-2026:21876-1","SUSE-SU-2026:21877-1","SUSE-SU-2026:21916-1","SUSE-SU-2026:21919-1","SUSE-SU-2026:2217-1","SUSE-SU-2026:2238-1","openSUSE-SU-2026:20826-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23446.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/069c8f5aebe4d5224cf62acc7d4b3486091c658a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3267bcb744ee8a2feabaa7ab69473f086f67fd71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4de6a43e8ecf961feabddf0e9d6911081d2ed218"},{"type":"WEB","url":"https://git.kernel.org/stable/c/621f2f43741b51f62d767eb4752fbcefe2526926"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98e8aed64614b0c199d5f0391fbe1a4331cb5773"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b87f361d41f9a7f1f6c426947ca815651c481376"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc06ac99fd78839b2d38850785731ef131d9ae26"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3e32a612c6391ca9b7c183aeec22b4fd24c300c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23446.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23446"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e58ba4544c7771591d1e3157bc01b4a8e4d1c3fc"},{"fixed":"cc06ac99fd78839b2d38850785731ef131d9ae26"},{"fixed":"b87f361d41f9a7f1f6c426947ca815651c481376"},{"fixed":"621f2f43741b51f62d767eb4752fbcefe2526926"},{"fixed":"4de6a43e8ecf961feabddf0e9d6911081d2ed218"},{"fixed":"3267bcb744ee8a2feabaa7ab69473f086f67fd71"},{"fixed":"d3e32a612c6391ca9b7c183aeec22b4fd24c300c"},{"fixed":"98e8aed64614b0c199d5f0391fbe1a4331cb5773"},{"fixed":"069c8f5aebe4d5224cf62acc7d4b3486091c658a"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23446.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.78"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.20"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23446.json"}}],"schema_version":"1.7.5"}
