Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Cortex-A7 的内存管理单元（MMU）模块端口在验证调用者提供的缓冲区时，仅对一个地址（即第一个字节）进行翻译。通用的模块管理器将模块实例、起始地址以及完整的字节大小传递给范围检查逻辑；然而，Cortex-A7 的实现却丢弃了模块实例和字节大小，仅向 MMU 查询了关于起始地址的单一问题。 因此，受内存保护的模块只要其起始字节对用户可读，无论后续范围延伸多远，都能通过范围检查。随后，特权调度代码会对该整个范围执行读取或写入操作。由于所有需要处理缓冲区或额外参数数组的受保护模块调度器都通过同一个宏调用该逻辑，该

Vulnerability Title
Cortex-A7 module data validation checks only the first address of a caller-supplied range
Source: CVE Program / CVE List V5
Vulnerability Description
The Cortex-A7 MMU Modules port validates a caller-supplied buffer by translating **one address** — the first byte. The common Module Manager hands its range check the module instance, the start address and the complete byte size; the Cortex-A7 implementation discarded the instance and the size and asked the MMU a single question about the start.
A memory-protected module therefore passed any range whose first byte was user-readable, however far the rest of it reached. Privileged dispatch code then read or wrote the whole range. Because every protected-module dispatcher that consumes a buffer or an extra-parameter array goes through this one macro, the defect is not in any individual service: it is in the primitive all of them rely on.
