Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
vsock/virtio: read virtqueues under worker locks<br />
<br />
Commit bd50c5dc182b ("vsock/virtio: add support for device<br />
suspend/resume") made the *_run flags transition from false to true when<br />
restore installs replacement virtqueues. The RX, TX and event workers<br />
read their virtqueue before locking and checking the corresponding flag,<br />
so a worker delayed across freeze and restore can observe the replacement<br />
queue&#39;s running state while retaining a pointer to the deleted queue.<br />
<br />
Read each virtqueue under its mutex after checking the run flag, keeping<br />
the pointer and state in the same queue generation.
