CVE-2023-43554

Memory corruption via FastRPC IOCTL handling

Published Jul 1, 2024 · Updated Aug 2, 2024

Memory corruption in Qualcomm Snapdragon FastRPC allows local users to cause unspecified impact through a crafted IOCTL request. The FastRPC IOCTL handler corrupts memory while processing the request, but Qualcomm has not disclosed the exact buffer or incorrect boundary operation. Local access is required, but no prior privileges or user interaction are required.
