Amd: >> Ryzen 5 4500u Security Vulnerabilities
A potential power side-channel vulnerability in
AMD processors may allow an authenticated attacker to monitor the CPU power
consumption as the data in a cache line changes over time potentially resulting
in a leak of sensitive information.

When SMT is enabled, certain AMD processors may speculatively execute instructions using a target
from the sibling thread after an SMT mode switch potentially resulting in information disclosure.

Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information.
