Google Chrome Patches 12 Vulnerabilities Including Actively Exploited V8 Zero-Day
Google has released a new set of security updates for its Chrome browser, fixing a total of 12 vulnerabilities. The patches were issued on September 3, 2026, and address issues that affect Windows, macOS, and Linux users.
The company shipped versions 152.0.7977.83 and 152.0.7977.82 for Windows and macOS, along with 152.0.7977.82 for Linux. This release comes just two days after a previous security update on September 1, indicating a rapid response to newly discovered threats.
None of the fixed flaws received a Critical severity rating. Ten of the issues are rated High, the second-highest level. The most significant among them is CVE-2026-85046, a type confusion vulnerability in the V8 JavaScript engine. The flaw was reported by a security researcher on August 4 and is already confirmed to be under active exploitation.
Other notable high-severity fixes include:
- CVE-2026-85045 – a race condition in V8
- CVE-2026-85048 – use-after-free in the Compositing component
- CVE-2026-85051 – another type confusion issue
These updates continue Google’s ongoing efforts to harden the browser against both publicly disclosed and zero-day threats.

Backdoor with Password 123456 and Hardcoded Keys: How AI Cracked 'Encrypted' USB Drives
An AI agent rapidly discovered critical cryptographic weaknesses in multiple USB encryption and copy-protection products, including hardcoded backdoor accounts and keys that bypassed user passwords entirely. In the SecZure YutianDun drive, two hidden accounts with passwords 123456 and SECZURE.COM allowed full decryption of files without the administrator password. NetacFileLock used a fixed AES-256 key embedded in the binary, ignoring the user password completely while also logging passwords in plaintext and employing ECB mode. KakaSoft USB Copy Protection relied on a modified MD5 implementation with altered shift constants and a hardcoded internal password derived from an embedded seed, enabling full Blowfish decryption without any user input. Nexcopy stored its Triple DES content key and IV in an encrypted configuration file protected only by a fixed 32-byte certificate inside the viewer application. The AI completed analyses in minutes that previously required hours of manual time-travel debugging and reverse engineering.
CVE-2026-98432: Temporary nftables Filter with Auto-Rollback for Ubuntu Servers
Administrators are deploying a temporary nftables-based mitigation for CVE-2026-98432 on Linux systems while awaiting official kernel patches. The filter drops IPv4 TCP packets with IP header length exceeding five, reducing exposure to the vulnerability. The procedure includes verifying kernel status via Canonical, preparing rollback commands, and using systemd timers to automatically remove the table after five minutes if connectivity is lost. Steps cover syntax validation with nft --check, integration with existing firewall configurations, and post-reboot verification to ensure the temporary table persists without interfering with ufw or Docker rules. Red Hat guidance on discarding packets containing IP options is referenced as a complementary measure. The process is designed for single-server testing before scaling to production fleets, with explicit instructions to avoid flush ruleset operations that could disrupt other tables.
Old iPhones Remain Vulnerable to Bootloader Exploits Despite Airplane Mode for Crypto Seed Storage
Founder of OneKey Ishi Wang has warned that resetting an old iPhone, enabling airplane mode, and storing a cryptocurrency wallet recovery phrase on the device does not provide reliable protection. Hardware vulnerabilities such as checkm8 affecting iPhone 4S through iPhone X and usbliter8 targeting A12 and A13 chips allow attackers with physical access to bypass the secure boot chain and execute code before iOS loads. These issues persist because the bootloader code cannot be overwritten through standard resets or iOS updates. While device passcode, Secure Enclave, and application-level encryption still serve as barriers, the risk level depends on the specific model, iOS version, and password strength. Wang advises against relying on disconnected older iPhones as cold storage solutions for seed phrases.
Docker Bypasses UFW Firewall Exposing PostgreSQL and Redis Ports to Rapid Malware Infections
A common Docker Compose setup with exposed database ports on fresh VPS instances allows attackers to compromise systems within minutes despite active UFW rules. Docker's use of DNAT rules in the PREROUTING chain and insertion of DOCKER-FORWARD chains before UFW rules in the FORWARD table routes external traffic directly to containers on internal bridge networks. IPv6 support in Docker versions 27 and later creates additional exposure vectors when administrators focus only on IPv4 protections or disable IPv6 filtering. Bots scan cloud IP ranges for open ports including 5432 and 6379, deploying miners such as kdevtmpfsi and kinsing or using Redis replication to load malicious modules. Historical cases include a Qdrant test instance on Hetzner compromised in under two minutes and similar issues reported in Spree Commerce starter templates. The article details Netfilter mechanics, protected-mode limitations in Redis, and specific exploitation techniques like CONFIG SET for cron jobs and CVE-2022-0543 Lua sandbox escapes.
