Yes. CVE-2025-21479, Qualcomm Multiple Chipsets Incorrect Authorization Vulnerability, is being exploited in the wild. CISA added it to its Known Exploited Vulnerabilities catalog on 3 Jun 2025, the day it was published. It affects Qualcomm Multiple Chipsets. If you run it, CISA's required action is: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

What it is

Multiple Qualcomm chipsets contain an incorrect authorization vulnerability. This vulnerability allows for memory corruption due to unauthorized command execution in GPU micronode while executing specific sequence of commands.

What to do

1. Check whether you run it. Look for Multiple Chipsets in your asset inventory, including appliances and cloud images. Stack check lists every exploited Qualcomm CVE at once.
2. Apply the fix. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 3 Jun 2025.
4. Get told next time. Email alerts when CISA adds a CVE for Qualcomm.
