Millions at Risk: Qualcomm Issues Urgent Warning After Critical Zero-Day Security Flaws Hit Snapdragon Devices
Qualcomm discovers and patches three critical zero-day vulnerabilities found in Snapdragon-powered Android devices—millions could be exposed.
- 3 new zero-days: CVE-2025-21479, -21480, -27038 confirmed in wild
- Critical impact: First two flaws score 8.6/10 in severity
- Millions affected: Snapdragon chips power hundreds of millions of devices globally
- Patch released: OEMs received fixes in May 2025
Are you carrying a ticking time bomb in your pocket? Qualcomm, a leader in wireless chipsets and the brains behind most Android phones, has just revealed three dangerous zero-day flaws hacking into devices running its popular Snapdragon processors.
These vulnerabilities, embedded in the Adreno GPU drivers, open the doors for hackers to execute malicious commands and potentially hijack your phone, tablet, or even your smart TV. Known as CVE-2025-21479, CVE-2025-21480, and CVE-2025-27038, these flaws have already been spotted in live attacks—making patching a race against time.
Security researchers at Google first sounded the alarm after detecting targeted exploits. Qualcomm has now rushed out a fix to device makers, but here’s the catch: it’s up to manufacturers like Samsung, Xiaomi, and others to actually deliver updates to your device.
Q&A: What Devices Are Vulnerable to Qualcomm’s Zero-Day Flaws?
Chances are high that if you own an Android device built since 2023—with a Snapdragon chip—it’s at risk. Qualcomm’s reach spans smartphones, tablets, laptops, wearables, and even IoT gadgets.
Android’s notoriously slow upgrade cycles mean some users may wait months before seeing any protection. Check for Android updates regularly and watch for urgent security patches from your device brand.
How Severe Are These Qualcomm Flaws?
Two of the vulnerabilities earned an alarming 8.6/10 critical rating. The third scores a significant 7.5/10. All three revolve around memory corruption, allowing attackers to bypass defenses and run unauthorized code, particularly during heavy graphics processing.
These aren’t theoretical bugs. Security teams have observed “limited, targeted exploitation,” signaling hackers are already leveraging these weaknesses against unsuspecting users.
How to Protect Your Device From Qualcomm Zero-Days
- Immediately check your settings for pending system updates.
- Contact your device maker (Samsung, OnePlus, etc.) for status if you don’t see an update.
- Consider turning on automatic updates and using trusted security software.
- Use a trusted antivirus and enable Play Protect on Android for added safety.
- Stay informed by following security advisories from sources like Qualcomm and Android.
What’s Next for Smartphone Security in 2025?
With cyberattacks becoming savvier, chip-based vulnerabilities like these highlight the urgent need for faster patch rollouts. Tech companies are pledging quicker response times, but until that becomes standard, user vigilance is key.
