Missing check for grant table
ISSUE DESCRIPTION The function gnttabcacheflush handles GNTTABOPcacheflush grant table operations. It checks to see if the calling domain is the owner of the page that is to be operated on. If it is not, the owner's grant table is checked to see if a grant mapping to the calling domain exists for...

x86: Mishandling of instruction pointer truncation during emulation
ISSUE DESCRIPTION When emulating HVM instructions, Xen uses a small i-cache for fetches from guest memory. The code that handles cache misses does not check if the address from which it fetched lies within the cache before blindly writing to it. As such it is possible for the guest to overwrite...
