In the Linux kernel, the following vulnerability has been resolved: net: usb: Remove disruptive netifwakequeue in rtl8150setmulticast syzbot reported WARNING in rtl8150startxmit/usbsubmiturb. This is the sequence of events that leads to the warning: rtl8150startxmit() { netifstopqueue(); usbsubmiturb(dev->txurb); } rtl8150setmulticast() { netifstopqueue(); netifwakequeue(); <-- wakes up TX queue before URB is done } rtl8150startxmit() { netifstopqueue(); usbsubmiturb(dev->txurb); <-- double submission } rtl8150setmulticast being the ndosetrxmode callback should not be calling netifstopqueue and notifstartqueue as these handle TX queue synchronization. The net core function devsetrxmode handles the synchronization for rtl8150setmulticast making it safe to remove these locks.
