affected hardware pre april 2019 intel x86 microprocessors website mdsattacks com zombieloadattack com the microarchitectural data sampling mds vulnerabilities are a set of weaknesses in intel x86 microprocessors that use hyper threading and leak data across protection boundaries that are architecturally supposed to be secure the attacks exploiting the vulnerabilities have been labeled fallout ridl rogue in flight data load zombieload 2 3 4 and zombieload 2 5 description edit the vulnerabilities are in the implementation of speculative execution which is where the processor tries to guess

researchers discovered the vulnerabilities in 2018 before anyone else 1 other researchers had agreed to keep the exploit confidential as well since 2018 9 on 14 may 2019 various groups of security researchers amongst others from austria s graz university of technology belgium s catholic university of leuven and netherlands vrije universiteit amsterdam in a disclosure coordinated with intel published the discovery of the mds vulnerabilities in intel microprocessors which they named fallout ridl and zombieload 1 6 three of the tu graz researchers were from the group who had discovered meltdown and spectre the year before 1 on 12 november 2019 a new variant of the zombieload attack called transactional asynchronous abort was disclosed 10 11 impact edit according to varying reports intel processors dating back to 2011 12 or 2008 1 are affected and the fixes may be associated with a performance drop 13 14 intel reported that processors manufactured in the month before the disclosure have mitigations against the attacks 1 intel characterized the vulnerabilities as low to medium impact disagreeing with the security researchers who characterized them as major and disagreeing with their recommendation that operating system software manufacturers should completely disable hyperthreading 1 15 nevertheless the zombieload vulnerability can be used by hackers exploiting the vulnerability to steal information recently accessed by the affected microprocessor 16 mitigation edit fixes to operating systems virtualization mechanisms web browsers and microcode are necessary 1 as of 14 may 2019 update applying available updates on an affected pc system was the most that could be done to mitigate the issues 17 intel incorporated fixes in its processors starting shortly before the public announcement of the vulnerabilities 1 on 14 may 2019 a mitigation was released for the linux kernel 18 and apple google microsoft and amazon released emergency patches for their products to mitigate zombieload 19 on 14 may 2019 intel published a security advisory on its website detailing its plans to mitigate zombieload 7 see also edit transient execution
