CVE-2023-33045Network attack vector

Remote memory corruption via malformed NAN S3 attribute

Published Nov 7, 2023 · Updated Aug 2, 2024

Buffer overflow in Qualcomm WLAN firmware allows remote attackers to corrupt memory via a crafted NAN management frame carrying an S3 attribute. The NAN management-frame parser copies the S3 attribute without validating its size, causing an out-of-bounds write in firmware memory. A transmitter with wireless reachability needs no authentication or user interaction; successful exploitation corrupts firmware execution and can interrupt wireless service.
