usb: aqc111: Do not perform PM inside suspend callback","description":"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->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
