CVE-2019-19339

Name of the Vulnerable Software and Affected Versions Red Hat Enterprise Linux 8 (affected versions not specified)

Description A flaw was found in the way Intel CPUs handle inconsistency between virtual to physical memory address translations in the CPU's local cache and system software's Paging structure entries. This issue can be exploited by a privileged guest user to induce a hardware Machine Check Error on the host processor, resulting in a severe DoS scenario by halting the processor. The vulnerability is related to the handling of virtual memory addresses and the invalidation of address translations in the processor's Translation Lookaside Buffer (TLB) cache.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
