VulnCheck KEV: CVE-2019-16098

The driver in Micro-Star MSI Afterburner 4.6.2.15658 aka RTCore64.sys and RTCore32.sys allows any authenticated user to read and write to arbitrary memory, I/O ports, and MSRs. This can be exploited for privilege escalation, code execution under high privileges, and information disclosure. These...

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls causing a kernel oops condition that results in a denial of service.
