CVE-2017-12134

Priority
Description
The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen
might allow local OS guest users to corrupt block device data streams and
consequently obtain sensitive memory information, cause a denial of
service, or gain host OS privileges by leveraging incorrect block IO
merge-ability calculation.
Ubuntu-Description
Jan H. Schönherr discovered that the Xen subsystem did not properly handle
block IO merges correctly in some situations. An attacker in a guest vm
could use this to cause a denial of service (host crash) or possibly gain
administrative privileges in the host.
