Notas de mapeo de vulnerabilidades
Justificación : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comentario : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Privilege Escalation
An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform. |
| CAPEC-663 |
Exploitation of Transient Instruction Execution
An adversary exploits a hardware design flaw in a CPU implementation of transient instruction execution to expose sensitive data and bypass/subvert access control over restricted resources. Typically, the adversary conducts a covert channel attack to target non-discarded microarchitectural changes caused by transient executions such as speculative execution, branch prediction, instruction pipelining, and/or out-of-order execution. The transient execution results in a series of instructions (gadgets) which construct covert channel and access/transfer the secret data. |
Notas
As of CWE 4.9, members of the CWE Hardware SIG are closely analyzing this entry and others to improve CWE's coverage of transient execution weaknesses, which include issues related to Spectre, Meltdown, and other attacks. Additional investigation may include other weaknesses related to microarchitectural state. As a result, this entry might change significantly in CWE 4.10.
