vduse: Fix race in vduse_dev_msg_sync and vduse_dev_read_iter

Published Aug 15, 2026 CVSS n/a EPSS < 1% KEV · Not listed

Description

In the Linux kernel, the following vulnerability has been resolved:

vduse: Fix race in vduse_dev_msg_sync and vduse_dev_read_iter

There is one race case in vduse_dev_msg_sync and vduse_dev_read_iter:

vduse_dev_read_iter():
lock(msg_lock);
dequeue_msg(send_list);
unlock(msg_lock);
vduse_dev_msg_sync():
wait_timeout() finish
lock(msg_lock);
check msg->complete is false
list_del(msg); <- double list_del() crash!

To fix this case, we shall ensure vduse_msg is on send_list or recv_list
outside the msg_lock critical section.
