CVE-2012-3432

Publication date 3 December 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service (guest OS crash) via unspecified operations on MMIO regions.
