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.

Android 0-day Vulnerability on Google Pixel Devices Actively Exploited in Attacks
Google patched CVE-2026-58704, an actively exploited Android zero-day allowing proximal privilege escalation via the Pixel cellular modem, urging the 2026-09-05 patch.
Google confirmed CVE-2026-58704, a high-severity elevation-of-privilege flaw in the Pixel cellular modem, is being exploited in limited, targeted attacks and shipped emergency fixes in the September 2026 Pixel Update Bulletin. The low-complexity bug requires no user interaction and enables proximal/adjacent privilege escalation with no additional execution privileges, phrasing Google has historically used for spyware-vendor and state-aligned zero-days. The Pixel bulletin patches 110 flaws including 12 critical RCEs, while the broader September Android update addressed roughly 180 vulnerabilities, including Wi-Fi memory-corruption bug CVE-2026-28662.

UNISOC Modem Flaw Enables Remote Code Execution via Video Calls
A UNISOC modem flaw allows attackers to achieve kernel-level remote code execution through malicious video calls on affected devices.
UNISOC, whose modems are widely deployed in Android smartphones, has a flaw that enables kernel-level code execution triggered via video calls. Successful exploitation would give an attacker deep control over affected handsets. No exploitation activity is mentioned in the report.

U.S. CISA adds Acronis Backup, Cisco ISE, and Google Pixel flaws to its Known Exploited Vulnerabilities catalog
CISA added actively exploited flaws in Cisco ISE, Acronis Backup, and Google Pixel (CVE-2026-76460, CVE-2026-87886, CVE-2026-58704) to its KEV catalog.
CISA added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog: CVE-2026-76460 (CVSS 10.0), an unauthenticated API authentication bypass in Cisco Identity Services Engine that Cisco confirms is being actively exploited; CVE-2026-87886, a local privilege escalation in the Acronis Backup plugins for cPanel/WHM and Plesk exploited in limited targeted attacks; and CVE-2026-58704 (CVSS 8.8), a Google Pixel cellular modem permission bypass exploited in limited, targeted attacks and patched in the September 2026 Pixel update. Under BOD 22-01, federal agencies must remediate KEV entries by the stated due dates. Google has not attributed the Pixel exploitation to any actor.

⚡ Weekly Recap: AI-Powered PLC Attacks, GitLab Attacks, Stripe Key Leaks and More
US agencies warn of AI-assisted attacks on exposed Siemens PLCs; the week also saw GitLab CVE-2026-19478 exploited and trojanized npm packages found.
The weekly recap leads with a US government warning that threat actors use AI-generated scripts and Censys/ZoomEye scanning to attack internet-exposed Siemens S7 PLCs in water, energy and manufacturing, calling it an active threat. Other stories include active exploitation of GitLab CVE-2026-19478 (CVSS 9.4, unauthenticated project rewriting), 14 trojanized npm packages delivering the RedC2 4.0 Linux backdoor, and the Zombie Card attack that revives expired Visa cards for contactless payment fraud. It also covers suspected Russian clusters UNC6293, UNC7005 and UNC5976 phishing campaigns, a faster Cloudflare Workers Spectre JWT leak, and a bespoke Cl0p JSP web shell deployed after exploiting PTC Windchill flaws.
