"value": "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"
