In the Linux kernel, the following vulnerability has been resolved: vduse: Fix race in vdusedevmsgsync and vdusedevreaditer There is one race case in vdusedevmsgsync and vdusedevreaditer: vdusedevreaditer(): lock(msglock); dequeuemsg(sendlist); unlock(msglock); vdusedevmsgsync(): waittimeout() finish lock(msglock); check msg->complete is false listdel(msg); <- double listdel() crash! To fix this case, we shall ensure vdusemsg is on sendlist or recvlist outside the msglock critical section.
