CVE-2024-45546

Local memory corruption via FIPS IOCTL processing

Published Jan 6, 2025 · Updated Jan 6, 2025

Buffer over-read in Qualcomm Snapdragon components allows local users to corrupt memory through a FIPS encryption or decryption IOCTL. The flaw occurs when the driver processes a user-space FIPS encryption or decryption IOCTL, but Qualcomm has not disclosed the faulty bounds operation or affected function. Low-privilege local access is required; the undisclosed corruption outcome prevents a narrower statement of data exposure or service interruption.
