A video call could give attackers kernel access on affected Unisoc phones
The exploit chain targets modem handling before the user meaningfully interacts with the call.
SOURCE · Dark ReadingTHE BRIEF
Researchers chained two flaws in Unisoc modem components to reach Android kernel-level access through VoLTE video-call processing. The risk depends on the device, firmware and carrier implementation.
WHY IT MATTERS
Kernel access sits below ordinary applications and can expose communications, credentials and device controls. Mobile patching is complicated because fixes must often pass through chipset vendors, phone makers and carriers.
WHO SHOULD CARE
Owners of affected Android devices, mobile fleets, telecom providers and high-risk users.
WHAT TO DO NOW
- Install the latest device and carrier security updates.
- Check whether the manufacturer lists the relevant modem fixes.
- Replace unsupported devices that no longer receive security patches.
