Px4 · Px4 · CVE-2023-47625
**Name of the Vulnerable Software and Affected Versions**
PX4 autopilot versions prior to 1.14.0
**Description**
A global buffer overflow vulnerability exists in the `CrsfParser TryParseCrsfPacket` function due to an invalid size check. This allows a malicious user to create an RC packet remotely, which can trigger the buffer overflow and cause the drone to behave unexpectedly.
**Recommendations**
For versions prior to 1.14.0, upgrade to version 1.14.0 to resolve the issue. As a temporary workaround, consider restricting access to the `CrsfParser TryParseCrsfPacket` function until the upgrade is applied.
