Local memory corruption via unchecked PhyID index
Published Sep 5, 2023 · Updated Aug 2, 2024
Memory corruption in Qualcomm Snapdragon WLAN HAL firmware allows local users to corrupt memory through a crafted PhyID in Tx status processing. The Tx status handler uses an improperly validated PhyID as an array index while processing WLAN transmission status. Low-privilege local access is required; corruption can compromise confidentiality, integrity, and availability within the unchanged security scope.
