This allowed a malicious x86 PV guest to access all of system memory, allowing for privilege escalation, DoS, and information leaks (XSA-241) - bsc#1061076: Multiple issues existed with the setup of PCI MSI interrupts that allowed a malicious or buggy guest to cause DoS and potentially privilege escalation and information leaks (XSA-237) - bsc#1055321: When dealing with the grant map space of add-to-physmap operations, ARM specific code failed to release a lock. This allowed a malicious guest administrator to cause DoS (XSA-235) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
