CVE-2017-15597

9.1

CRITICAL · CVSS 3.0 · EPSS 2.8% (pctl 86)

In your normal cycle

Critical by CVSS (9.1), but no sign of active exploitation.

Description

An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out.
