CVE intelligence and bounded remediation

CVE-2019-15948 — Ti Cc256Xc-Bt-Sp Firmware security vulnerability

High CVSS 8.8

Texas Instruments CC256x and WL18xx dual-mode Bluetooth controller devices, when LE scan mode is used, allow remote attackers to trigger a buffer overflow via a malformed Bluetooth Low Energy advertising packet, to cause a denial of service or potentially execute arbitrary code. This affects CC256xC-BT-SP 1.2, CC256xB-BT-SP 1.8, and WL18xx-BT-SP 4.4.

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.
