CRITICAL9.1EPSS 1.5%Published: 10/30/2017Modified: 12/3/2025
Also known as:ALPINE-CVE-2017-15597DEBIAN-CVE-2017-15597
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.
Affected packages (2)
- Alpine/xenfrom 0, < 4.9.0-r7
- Debian/xenfrom 0, < 4.8.2+xsa245-0+deb9u1
