Executive brief
A memory corruption vulnerability exists in Qualcomm components when validating large data buffers from external sources. The vulnerability stems from an incorrect buffer length check that uses addition instead of proper bounds validation. An attacker could exploit this to corrupt memory and potentially execute arbitrary code or cause denial of service.
Technical details
The vulnerability is a memory corruption issue (CWE-190 / integer overflow related) in buffer validation logic. The vulnerable code uses addition when performing buffer length checks, leading to an integer overflow or wraparound condition that bypasses intended bounds validation. An attacker can supply specially crafted large data buffers to trigger the flaw. The vulnerability requires the ability to send or provide data to the affected component but does not require authentication. Successful exploitation could lead to memory corruption, information disclosure, or arbitrary code execution depending on memory layout and context.
