CVE-2022-33275

Memory corruption via out-of-range WLAN array index

Published Sep 5, 2023 · Updated Feb 27, 2025

Memory corruption in the WLAN HAL of Qualcomm Snapdragon chipsets allows local users to corrupt memory via an out-of-range lm_itemNum. The HAL uses lm_itemNum as an array index without adequately validating that the received value is within range. Local access is required, but no existing privileges or user interaction is needed; successful exploitation can disclose or alter data or interrupt service.
