Publication date 20 November 2013

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Memory leak in the __kvm_set_memory_region function in virt/kvm/kvm_main.c in the Linux kernel before 3.9 allows local users to cause a denial of service (memory consumption) by leveraging certain device access to trigger movement of memory slots.

From the Ubuntu Security Team
