High CVSS 8.8

Cypress : https://www.infineon.com/ Cypress Bluetooth Mesh SDK BSA0107_05.01.00-BX8-AMESH-08 is affected by: Buffer Overflow. The impact is: execute arbitrary code (remote). The component is: affected function is pb_transport_handle_frag_. ¶¶ In Cypress Bluetooth Mesh SDK, there is an out-of-bound write vulnerability that can be triggered during mesh provisioning. Because there is no check for mismatched SegN and TotalLength in Transaction Start PDU.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
