Information disclosure via Bluetooth command buffer over-read
Published Jan 6, 2023 · Updated Apr 9, 2025
Information disclosure in Qualcomm Snapdragon Bluetooth HOST allows physically proximate attackers to read memory via peer-device commands. Bluetooth HOST processes GetFolderItems and GetItemAttribute commands without keeping reads within the command buffer, causing an out-of-bounds read. Exploitation requires Bluetooth access from a peer device; the disclosed consequence is exposure of memory contents, with no reported data modification.
