CVE-2026-25283: Qualcomm buffer overflow in external data handling

CVE-2026-25283 · Severity: high · CVSS 8.8 · Published 2026-09-17

Executive brief

A memory corruption vulnerability exists in Qualcomm components when handling unverified data from external sources. Unvalidated input exceeding allocated buffer sizes can corrupt memory, potentially allowing attackers to crash the system or execute arbitrary code, impacting device stability and security.

Technical details

This is a classic buffer overflow vulnerability in Qualcomm firmware or components that processes external data without proper size validation. When copying data from an untrusted external source, the code fails to verify the input size against the allocated buffer, leading to a heap or stack overflow. The vulnerability requires network or local access to send malformed data to the affected component. Exploitation can result in denial of service (crash) or potentially remote code execution depending on the memory layout and exploitation technique used.
