Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The KVM subsystem in the Linux kernel before 3.6.9, when running on hosts that use qemu userspace without XSAVE, allows local users to cause a denial of service (kernel OOPS) by using the KVM_SET_SREGS ioctl to set the X86_CR4_OSXSAVE bit in the guest cr4 register, then calling the KVM_RUN ioctl.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL15797.
