Last modified Jun 17, 2026

CVE-2014-8134 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value.. EPSS estimates a 0.70% chance of exploitation in the next 30 days.
