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.

F´（F Prime）是一个用于开发和部署太空飞行及其他嵌入式软件应用的框架。在 4.3.0 版本之前，Svc::FileDownlink 组件中的 SendPartial 函数存在范围验证漏洞。该漏洞的原因在于：求和过程中发生了整型环绕（wrap-around），导致绕过文件范围验证，最终使 m_endOffset 被错误设置，而 m_byteOffset 大于环绕后的结束偏移量。 当现有源文件的大小大于传入的 startOffset，且调用方可控制 SendPartial 所指定的长度与该偏移量之和发生 U32

Vulnerability Title
F´: SendPartial Integer Overflow Leading to Assertion DoS
Source: CVE Program / CVE List V5
Vulnerability Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileDownlink SendPartial range validation is vulnerable because the wrapping sum bypasses file-range validation, becomes m_endOffset, and leaves m_byteOffset greater than the wrapped end offset. When an existing source file is larger than the supplied startOffset and a caller able to issue SendPartial supplies a length whose U32 sum with that offset wraps, the first data-packet send reaches FW_ASSERT and aborts or resets the process, causing denial of service. This issue is fixed in version 4.3.0.
