CVE-2026-21385 is a high-severity vulnerability in an open-source Qualcomm graphics or display component used by Android devices and numerous Qualcomm chipsets. Available reporting consistently describes the flaw as an integer overflow or wraparound during memory allocation alignment handling that leads to memory corruption in the graphics subcomponent. Some reporting further characterizes the resulting condition as a buffer over-read capable of exposing sensitive memory contents. The issue affects a very large set of Qualcomm platforms and was included in the March 2026 Android security updates. Google and Qualcomm indicated that the vulnerability was under limited, targeted exploitation, and CISA added it to the Known Exploited Vulnerabilities catalog.
