Four new vulnerabilities in Intel processors have been identified and can be used through side-channel attacks. The vulnerabilities are called RIDL, Fallout and ZombieLoad.
These vulnerabilities allow attackers to steal passwords access, The wrenches encryption or any other type of data that is loaded or stored in the CPUs buffer memory.
The vulnerabilities are categorized as Microarchitectural Data Sampling (MDS) and are identified by the following four CVEs:
- CVE-2018-12126 - Microarchitectural Store Buffer Data Sampling (MSBDS)
- CVE-2018-12130 - Microarchitectural Fill Buffer Data Sampling (MFBDS)
- CVE-2018-12127 - Microarchitectural Load Port Data Sampling (MLPDS)
- CVE-2019-11091 - Microarchitectural Data Sampling Uncacheable Memory (MDSUM)
The researchers who announced the vulnerabilities, in addition to baptizing them (sic), also created two different websites, from which you can read more:
You should know that all solutions The current patches are just mitigations and do not completely fix the vulnerabilities. To fully resolve these vulnerabilities, all vendors state that you will need to disable hyper-threading, which will affect your computer.
