Unisoc VoLTE Video Call Exploit Chain Can Give Attackers Full Android Kernel Access

Unisoc modem firmware flaw CWE-1189 allows VoLTE video call RCE chain to gain full Android kernel access on T606/T612/T7250 chipsets; no patch yet.

SSD Secure Disclosure published the second stage of an exploit chain, first disclosed in March 2026, that achieves full Android kernel access on Unisoc modem firmware via a VoLTE video call. The privilege-escalation flaw, classified as CWE-1189 (Improper Isolation of Shared Resources on System-on-a-Chip), exploits shared physical memory between modem and application processor with no hardware boundary, letting modem code map the entire 32-bit address space and modify Android kernel pages via ARM Memory Protection Unit registers. Confirmed affected chipsets include Unisoc T606 (Motorola E13), T612 (Realme C33), and T7250 (Xiaomi Redmi A5), sold across more than 140 countries. No CVE has been assigned, the August 2026 Android Security Bulletin does not address it, and Unisoc has not responded to researchers; exploitation requires an attacker-controlled private 4G network and a victim answering the call.

Critical Check Point VPN Vulnerabilities Enable Remote Code Execution Attacks

Check Point patched two critical VPN flaws, CVE-2026-85102 and CVE-2026-85103 (CVSS 9.8), allowing unauthenticated RCE on Security Gateways.

Check Point disclosed and patched two critical VPN vulnerabilities, CVE-2026-85102 (improper certificate trust validation, CWE-295) and CVE-2026-85103 (heap-based buffer overflow in ASN.1 certificate parsing, CWE-122), both rated CVSS 9.8 and exploitable for unauthenticated remote code execution under specific conditions. The flaws affect Security Gateway, Security Management Server, and Spark Firewall deployments on R81.20, R82, and R82.10 branches plus end-of-support versions such as R80.40 and R81, while R82.20 is not affected. Check Point reports no evidence of active exploitation or public PoC; Live Patch rollout began September 9, 2026, and administrators without it must install Jumbo Hotfix Accumulator builds (R82.10 Take 44+, R82 Take 126+, R81.20 Take 166+). For Site-to-Site VPN, restricting UDP ports 500 and 4500 to known peers serves as an interim workaround, but no mitigation exists for Remote Access VPN or Spark Firewalls.
