CVE-2022-31364

Code execution via inconsistent segmented-packet SegN

Published Feb 1, 2023 · Updated Mar 27, 2025

Out-of-bounds write in Infineon Cypress Bluetooth Mesh SDK BSA0107_05.01.00-BX8-AMESH-08 allows physically proximate attackers to execute code. The lower_transport_layer_on_seg function writes beyond buffer bounds when a series of segmented Bluetooth Mesh packets contains inconsistent SegN values. Bluetooth Mesh radio access is required, and successful memory corruption grants code execution in the affected device context.
