CVE-2022-33295Network attack vector

Information disclosure via WMS parser buffer over-read

Published Apr 4, 2023 · Updated Aug 3, 2024

Buffer over-read in the modem WMS parser in Qualcomm Snapdragon allows remote attackers to disclose memory with a crafted WMS message. The parser reads beyond the supplied buffer boundary while processing a WMS message whose content conflicts with its stated length. No privileges or user interaction are required; memory disclosure is the documented concrete consequence, while Qualcomm does not describe the low availability effect.
