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.

Hackers exploit Tencent app flaw to deploy GrayRabbit malware

UNC3569 actively exploits one-click RCE in Tencent Sogou Input Method to deploy the GrayRabbit backdoor, patched in version 16.3.0.3498.

Gen Digital reports that China-aligned UNC3569 is actively exploiting CVE-2026-51990, a one-click RCE chain in Tencent Sogou Input Method for Windows, which has hundreds of millions of installations in China. The chain abuses unvalidated command-line argument injection via the sgbiz: URI handler, unrestricted URL navigation in a CEF-based webview, and an unsandboxed outdated Chromium 80 engine to gain code execution and install the GrayRabbit backdoor. The analyzed malware is a mature 64-bit variant with RC4-encoded C2 config supporting reverse shells, file transfer, and reflective plugin loading. Tencent patched the argument validation in version 16.3.0.3498, but the browser engine remains outdated and unsandboxed.
