**Name of the Vulnerable Software and Affected Versions** AMD processors (affected versions not specified) **Description** A potential issue in AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack, potentially enabling information disclosure. The vulnerability is related to the implementation of Dynamic Voltage and Frequency Scaling (DVFS) in AMD processor microcode, which is associated with inadequate protection of physical side channels. Exploitation of the issue may allow a remote attacker to gain unauthorized access to protected information using a side channel. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Intel(R) Processors (affected versions not specified) **Description** The issue is related to observable behavioral power management throttling and errors in the dynamic frequency adjustment process of Intel processor microcode, specifically concerning Dynamic Voltage and Frequency Scaling (DVFS) technology. This may allow an authenticated user or a remote attacker to potentially enable information disclosure via network access or side-channel attacks. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
