CVE-2023-33028Network attack vector

Memory corruption via oversized PMK cache copy

Published Oct 3, 2023 · Updated Feb 27, 2025

Stack-based buffer overflow in Qualcomm Snapdragon WLAN firmware allows remote attackers to corrupt memory during PMK cache handling. The closed-source firmware copies PMK cache data into a stack buffer without validating the input size. No authentication or user interaction is required, but Qualcomm has not disclosed whether the resulting corruption causes a crash or permits code execution.
