CVE-2026-21385 is a high-severity vulnerability in an open-source Qualcomm Graphics or Display component used across a large number of Qualcomm chipsets integrated into Android devices. Available reporting consistently describes the flaw as an integer overflow or wraparound that leads to memory corruption during memory allocation alignment handling. Some reporting further characterizes the resulting condition as a buffer over-read in the Graphics component, indicating that malformed size or alignment calculations can cause out-of-bounds memory access. Qualcomm indicated the issue affects roughly 234 to 235 chipsets, and Google confirmed the vulnerability was under limited, targeted exploitation. The flaw was addressed in the March 2026 Android security updates and corresponding Qualcomm security bulletin.
