CVE-2025-21480 Qualcomm Multiple Chipsets: login or permission bypass

In plain words: A door that should be locked is not: part of the system can be reached without a valid login or permission. The attacker gets in as a user or administrator without knowing a password.

Confirmed exploited by CISA on · US federal patch deadline Jun 24, 2025

What to do

  1. Install Qualcomm's security update for Multiple Chipsets. If no update exists, follow the vendor's workaround or stop using the product until one ships.
  2. Install system updates the day they come out — most phone zero-days are fixed in a point release.
  3. Restart your phone every few days; some spyware does not survive a reboot.
  4. If you are a journalist, activist, lawyer, politician or executive, turn on Lockdown Mode (iPhone) or Advanced Protection (Android).

Who is affected

Could reach you. This one is aimed at devices or apps of the kind people own.

What's at risk: Messages, photos, location, microphone and camera. The most serious ones are "zero-click": no tap needed from the owner. They are usually used as spyware against a small number of chosen people.
