Short explanation
CVE-2026-92160 is an integer overflow vulnerability affecting the Svc::FileDownlink component in F´. Wrapping U32 sums bypass file-range validation and trigger FW_ASSERT, causing a denial of service.
It allows an authorized caller to manipulate inputs to abort or reset processes, resulting in a denial of service.
What should be done?
- Follow vendor advisories to apply necessary updates
Chain of evidence and sources
CVE-2026-92160, F´ sürüm 4.3.0 öncesindeki Svc::FileDownlink SendPartial fonksiyonunu etkiler.
U32 toplamının sarması, dosya aralığı doğrulamasını atlayarak FW_ASSERT hatasına ve DoS durumuna yol açar.
Show the technical text from the sources
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.
