Improper Restriction of Operations within the Bounds of a Memory Buffer
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile and Snapdragon Wear MDM9206, MDM9607, MDM9640, MDM9650, SD 210/SD 212/SD 205, SD 425, SD 430, SD 450, SD 600, SD 625, SD 650/52, SD 808, SD 810, SD 820, SD 835, and SDX20, in pre-auth request, Host driver uses FT IEs sent by the supplicant. A buffer overflow may occur if FT IEs sent by the supplicant are larger than the expected value.
CWE-119 - Buffer Overflow
Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
