This vulnerability exists in Qualcomm Snapdragon automotive and mobile platform components affecting Android devices released before the 2018-04-05 security patch level. The flaw resides in the GPT (GUID Partition Table) listener implementation where improper validation of buffer offsets leads to a classic buffer overflow condition. When processing partition table responses, the system fails to adequately verify the size and offset parameters of incoming data structures, creating an opportunity for malicious input to overwrite adjacent memory regions. This vulnerability specifically impacts a wide range of Qualcomm Snapdragon chipsets including the MDM9206, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 425, SD 430, SD 450, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 800, SD 808, SD 810, SD 820, SD 820A, and SD 835 processors. The buffer overflow condition represents a CWE-121 vulnerability classified as a stack-based buffer overflow, which falls under the broader category of memory safety issues. This weakness allows attackers to potentially execute arbitrary code with elevated privileges, as the overflow can overwrite critical program execution structures including return addresses and function pointers. The operational impact is significant given that these chipsets are deployed in automotive infotainment systems and mobile devices where they handle critical system functions including partition management and boot processes. Attackers could exploit this vulnerability to gain unauthorized access to device functionality, potentially compromising vehicle systems or mobile device security. The vulnerability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, as successful exploitation could enable attackers to execute malicious code on affected devices. Mitigation strategies should include immediate deployment of the relevant Android security patches, implementation of input validation controls, and monitoring for anomalous GPT partition table access patterns. System administrators should also consider firmware updates for automotive systems that rely on these Qualcomm processors, as the vulnerability could potentially be exploited to compromise vehicle safety systems. The flaw demonstrates the importance of proper input validation in embedded systems and highlights the need for comprehensive security testing of low-level system components that handle critical data structures. Organizations should implement continuous monitoring for exploitation attempts and ensure that all affected devices receive timely security updates to prevent potential compromise of sensitive automotive or mobile device functions.
