Description Robert Frohl 2022-02-10 12:49:01 UTC 
rh#2049558

Out of bounds read under complex microarchitectural condition in memory subsystem for some Intel Atom(R) Processors may allow authenticated user to potentially enable information disclosure or cause denial of service via network access. Under complex microarchitectural conditions user to supervisor page fault can be potentially missed which cause a malicious application to read some portion of operating system memory or could cause temporary denial of service.
