Intel describes the exploited vulnerabilities as "Microarchitectural Data Sampling" (MDS) - where "sampling" is another way...
Microarchitectural Data Sampling Uncacheable Memory (MDSUM) CVE-2019-11091 Core or data accesses that use the uncacheable (UC) memory type do not fill new lines into the processor caches. On processors affected by Microarchitectural Data Sampling Uncachable Memory (MDSUM), ...
Four new microprocessor flaws have been discovered, the most severe of which is rated by Red Hat Product Security as having an Important impact. These flaws, if exploited by an attacker with local shell access to a system, could allow data in the CPU’s cache to be exposed to unauthorized...
Microarchitectural Data Sampling(MDS) is a CPU side vulnerability. According to Intel, its CPU has some loose points that can be exploited by hackers. This means taking control of the CPU to be able to read very short term data stored in CPU internal buffers. Let’s see how it works. We...
Intel officially released a group of microarchitecture data sampling (MDS) vulnerabilities. An attacker with local access to a targeted system may exploit these vulnerabilities to obtain data on the targeted system, causing some information leakage. (Vulnerability ID: HWPSIRT-2019-05136, HWPSIRT-2019...
