Denial of Service and Privilege Escalation Vulnerability in Xen 4.4.x on ARM Systems

CVE-2014-5148 · MEDIUM Severity

AV:L/AC:L/AU:N/C:P/I:P/A:P

Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process.
