CVE-2025-27038 Qualcomm Multiple Chipsets: memory-safety flaw

In plain words: The program mishandles the memory it uses to keep track of data. A specially made input can scramble that memory. Usually lets an attacker crash the program or run their own code with its permissions.

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.
