CIS/MS-ISAC issued an advisory covering a large batch of vulnerabilities in Google Chrome versions prior to 151.0.7922.108/.109, affecting Windows, Mac, and Linux. The flaws span multiple Chrome components including WebGL, V8, Skia, GPU, Media, Views, and Extensions, with root causes ranging from use-after-free and heap buffer overflow to out-of-bounds write and integer overflow bugs. The most severe of these could allow arbitrary code execution in the context of the logged-on user, potentially enabling an attacker to install programs, manipulate data, or create new accounts depending on user privileges.
At the time of publication, there were no reports of active exploitation in the wild. The advisory maps the exploitation pathway to the Drive-By Compromise technique under the Initial Access tactic, indicating that a user visiting a malicious or compromised webpage could trigger exploitation without further interaction. Given the breadth of the patch set, organizations are urged to prioritize testing and deployment of the update across managed browser fleets.
Recommended mitigations focus on standard patch management and browser hardening practices: automated patch deployment, least-privilege account configurations, exploit protection features (DEP, WDEG, SIP/Gatekeeper), DNS and URL filtering, and user awareness training against phishing and malicious links. No specific threat actor, malware family, or campaign is associated with these vulnerabilities in this advisory.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
