CVE-2025-21450 is a critical vulnerability in Qualcomm GPS/GNSS components caused by the use of an insecure connection method when downloading GNSS assistance data. Available reporting indicates the GPS firmware retrieves assistance data over unencrypted HTTP and does not properly authenticate the downloaded content. This allows an on-path attacker to intercept and modify the data in transit, defeating the integrity assumptions of the GNSS assistance workflow. Because the flaw affects a closed-source Qualcomm component used across a broad chipset ecosystem, exploitation can influence device positioning and timing functions that depend on the manipulated assistance data.
