CVE-2026-25302 · Severity: high · CVSS 7.1 · Published 2026-10-06

Qualcomm chipsets fail to properly verify cryptographic signatures when processing non-ELF partition images. An attacker can bypass authentication checks and load unsigned or corrupted images, potentially gaining code execution or compromising system integrity on affected devices.

## Technical details

A cryptographic validation flaw in Qualcomm's partition processing logic allows signature and authentication checks to be bypassed for non-ELF formatted partitions. The vulnerability enables loading of unsigned or corrupted images, which could lead to arbitrary code execution or system compromise depending on which partition is affected.
