Technical description

Compiler Optimization Removal or Modification of Security-critical Code vulnerability in IntPeParseUnwindData() results in multiple dereferences to the same pointer. If the pointer is located in memory-mapped from the guest space, this may cause a race-condition where the generated code would dereference the same address twice, thus obtaining different values, which may lead to arbitrary code execution. This issue affects: Bitdefender Hypervisor Introspection versions prior to 1.132.2.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
