[PATCH 0/6] Fix XSA-155-like bugs in frontend drivers

From: Marek Marczykowski-GÃrecki
Date: Mon Apr 30 2018 - 17:05:31 EST

Patches in original Xen Security Advisory 155 cared only about backend drivers
while leaving frontend patches to be "developed and released (publicly) after
the embargo date". This is said series.

Marek Marczykowski-GÃrecki (6):
xen-netfront: copy response out of shared buffer before accessing it
xen-netfront: do not use data already exposed to backend
xen-netfront: add range check for Tx response id
xen-blkfront: make local copy of response before using it
xen-blkfront: prepare request locally, only then put it on the shared ring
