Summary
In various Android implementations utilizing Qualcomm's drivers, a vulnerability allows userspace to send Information Elements (IEs) to the host driver in a manner that may cause an integer variable, which tracks the length of data, to overflow. This could potentially lead to a heap buffer overflow when multiple append commands are issued. Such an overflow might compromise the system’s memory, enabling malicious actors to execute arbitrary code, thereby increasing the risk of exploitation.
