TITLE

AMD Ryzen Processor AGESA Service disruption in microcode (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2017-002660

DESCRIPTION

The AMD Ryzen processor with AGESA microcode through 2017-01-27 allows local users to cause a denial of service (system hang) via an application that makes a long series of FMA3 instructions, as demonstrated by the Flops test suite. AMDRyzen is a processor of American Advanced Micro Devices (AMD). An attacker could exploit the vulnerability to cause a denial of service and refuse to provide services to legitimate users
