MS-ISAC advisory 2026-082 details five use-after-free vulnerabilities in Google Chrome affecting versions prior to 151.0.7922.137/.138 (Windows/Mac) and 151.0.7922.137 (Linux). The flaws span multiple Chrome components including V8, TabStrip, Extensions, HTML, and Blink. Successful exploitation could allow an attacker to execute arbitrary code in the context of the logged-on user, potentially enabling installation of programs, data manipulation, or creation of new accounts, with impact scaled to the victim's privilege level.
There are currently no reports of these vulnerabilities being exploited in the wild. The advisory recommends standard mitigations including prompt patching, least-privilege enforcement, browser sandboxing, exploit protection features, and web-content restrictions. This is a routine browser patch advisory rather than an active threat campaign.

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 16,436 reports from 149 sources, 661 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.
