Preface: An automotive cockpit is the driver’s compartment, integrating all the controls and information displays needed to operate a vehicle, including the steering wheel, dashboard, instruments, and central displays.
Background: To install QNX on a Qualcomm SA8775P chip, you will need the specific QNX Board Support Package (BSP) for that platform, as it contains the necessary hardware-specific software to get the OS running. The installation process will involve loading the BSP onto the chip, which provides the essential startup code and device drivers needed to run QNX. Since this is an automotive-grade chip used for cockpit and driving functions, it’s likely an OEM or a specialized automotive development partner would be handling this process.
QNX handles guest virtual machine (GVM) memory by using a hypervisor to manage the host physical memory, which the guest sees as contiguous. The hypervisor allocates memory to a guest and uses services like “smmuman” to program the IOMMU/SMMU to protect the guest’s memory from the host and other guests. The hypervisor maps host physical memory to the guest’s guest-physical memory, and can use shared memory regions for efficient inter-VM communication.
Vulnerability details:
Title – Exposed Dangerous Method or Function in Automotive Software platform based on QNX
Description – Memory corruption while processing request sent from GVM.
Technology Area – Automotive Software platform based on QNX
Vulnerability Type – CWE-749: Exposed Dangerous Method or Function
Access Vector Local
Security Rating High
CVSS Rating High
CVSS Score 7.8
Due to a lack of detailed supplier information, we discovered through observation that…
Attack Surface:
- Shared memory + IPC exposed to guest.
Threats:
- Buffer overflow → hypervisor memory corruption.
- Capability spoofing → unauthorized access.
Mitigations:
- Mediator validation.
- Capability-based security.
- Immutable protocol with checksum.
