CVE-2013-5634: arch/arm/kvm/arm.c in the Linux kernel before 3.10 on the ARM platform, when KVM is used, allows host OS us...

Security readout for executives and security teams

This is a Linux kernel crash risk affecting ARM systems that use KVM virtualization. A local host user could trigger a kernel NULL pointer fault through a KVM ioctl path, potentially crashing the host. That matters most for ARM virtualization hosts where host downtime affects multiple workloads. Likely limited to older ARM Linux hosts running KVM, especially virtualization infrastructure still on kernels before 3.10 or vendor kernels missing the upstream fix. Treat as a stability and availability risk for legacy ARM virtualization hosts. Prioritize if affected hosts run business-critical workloads or multi-tenant environments. Mitigation focus: Upgrade to Linux kernel 3.10 or a vendor-supported kernel containing the fix.; Confirm vendor advisories for backported fixes on long-term or distribution kernels.; Limit host shell access on ARM KVM virtualization systems..
