Name of the Vulnerable Software and Affected Versions Systems with microprocessors (affected versions not specified)

Description The issue is related to microprocessors utilizing speculative execution and branch prediction, which may allow unauthorized disclosure of information to an attacker with local user access. This is achieved through a speculative buffer overflow and side-channel analysis. The vulnerability is associated with the branch prediction module's functionality in Intel, ARM, and AMD processors. Exploitation of the vulnerability enables an attacker to disclose protected information by creating conditions for incorrect branch prediction.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
