What is CVE-2026-41144?

A logic bug in the F Prime framework prior to version 4.2.0 allows for an attacker to bypass bounds checks on file writes, leading to potential remote code execution. An attacker can craft a DataPacket that exploits the overflow of byte offsets, writing arbitrary data to any file at any offset without proper sanitization of the destination file path. This allows unauthorized modifications and manipulations within embedded systems. The issue is not detected by ASAN due to valid buffer access during memory operations. A patch is available in version 4.2.0, with no known workarounds.

Affected Version(s)

fprime < 4.2.0
