CVE-2019-14085

Unspecified impact via unchecked WLAN integer underflow

Published Mar 5, 2020 · Updated Aug 5, 2024

Integer underflow in Qualcomm Snapdragon WLAN firmware allows local users to cause unspecified impact through user-supplied data. A WLAN firmware function fails to validate data received from user space before performing an integer operation, allowing the result to underflow. Local low-privileged access is required, and Qualcomm has not disclosed the affected function, input format, or resulting memory operation.
