DescriptionNVD

Memory corruption when IOCTL call is invoked from user-space to write board data to WLAN driver.

AnalysisAI

Memory corruption when IOCTL call is invoked from user-space to write board data to WLAN driver. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Memory corruption when IOCTL call is invoked from user-space to write board data to WLAN driver. Affected products include: Qualcomm Aqt1000 Firmware, Qualcomm Fastconnect 6200 Firmware, Qualcomm Fastconnect 6700 Firmware, Qualcomm Fastconnect 6800 Firmware, Qualcomm Fastconnect 6900 Firmware.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
