CVE-2020-3616

Memory corruption via unchecked strcpy copy

Published Jun 2, 2020 · Updated Aug 4, 2024

Classic buffer overflow in Qualcomm Snapdragon display firmware allows local users to corrupt memory through an oversized input. The display function passes an attacker-controlled value to strcpy without first validating that its length fits the destination buffer. Low-privilege local access is required; successful exploitation allows reading or altering protected data and interrupting the affected component.
