Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from not refreshing the asynchronous PF work queue when the vCPU is destroyed...

Supermicro BMC PMBus Physical Destruction

The vulnerability of the PMBus interface of the VRM Voltage Regulator Module in Supermicro BMC controllers is related to the improper assignment of permissions for the critical resource. Exploiting this vulnerability may allow an attacker to physically disable the CPU without the possibility of...

SUSE CVE-2018-5244

In Xen 4.10, new infrastructure was introduced as part of an overhaul to how MSR emulation happens for guests. Unfortunately, one tracking structure isn't freed when a vcpu is destroyed. This allows guest OS administrators to cause a denial of service host OS memory consumption by rebooting many...
