Alert meAnalysisAI
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. Rated high severity (CVSS 8.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.

Technical ContextAI · show details
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. 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. Affected products include: Ti Cc256Xc-Bt-Sp Firmware, Ti Cc256Xb-Bt-Sp Firmware, Ti Wl18Xx-Bt-Sp Firmware.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
