Service interruption via FT element buffer over-read
Published Jun 6, 2023 · Updated Aug 2, 2024
Buffer over-read in Qualcomm WLAN firmware allows remote attackers to interrupt wireless service through crafted Fast Transition information elements. The FT information-element parser reads past its supplied buffer while processing remotely supplied wireless-management data. No credentials or user interaction are required; successful exploitation transiently disrupts WLAN service without reported disclosure or modification.
