Summary:<\/p>\n
AMD processors may allow a privileged local attacker to further escalate their
privileged and execute arbitrary code within the processor’s firmware layer.<\/p>\n
Software Description:
– amd64-microcode: Platform firmware and microcode for AMD CPUs and SoCs<\/p>\n
Details:<\/p>\n
Enrique Nissim and Krzysztof Okupski discovered that some AMD processors
did not properly restrict access to the System Management Mode (SMM)
configuration when the SMM Lock was enabled. A privileged local attacker
could possibly use this issue to further escalate their privileges and
execute arbitrary code within the processor’s firmware layer.<\/p>\n
