Use after free in Passwords in Google Chrome on Mac prior to 149.0.7827.53 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Remote heap corruption in Google Chrome on macOS prior to 149.0.7827.53 stems from a use-after-free in the Passwords component, letting a remote attacker who lures a user into specific UI interactions trigger memory corruption via a crafted HTML page. Chromium rates the underlying flaw Critical and a vendor patch is available, though no public exploit has been identified at time of analysis and active exploitation has not been confirmed by CISA KEV.

Technical ContextAI

The defect is a CWE-416 use-after-free in Chrome's Passwords subsystem (the browser-side password manager UI/storage flow) on the macOS build of the Chromium-based browser identified by CPE strings tied to Google Chrome 149.x. Use-after-free occurs when code dereferences a heap object after it has been freed, allowing an attacker who can groom the heap (typical via JavaScript allocations in a crafted page) to reuse the freed slot with attacker-controlled data and corrupt object metadata or vtables. In Chrome, such bugs in renderer-adjacent components can lead to type confusion and arbitrary read/write in the affected process, and when combined with the right UI gesture path through the Passwords feature, the freed object is reachable from web content.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 for macOS - upgrade all macOS endpoints to this version or later via the Chrome stable channel as documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html, and force-restart browsers so the new binary is loaded. If immediate patching is blocked, compensating controls include disabling Chrome's built-in password manager (chrome://settings 'Offer to save passwords' off, and 'Auto Sign-in' off) to reduce reachability of the vulnerable Passwords code paths - trade-off is loss of autofill for users who rely on it; enforcing a managed policy that blocks untrusted sites via SafeSites/URL allowlisting reduces the chance a user lands on a crafted page but does not eliminate the bug; and advising users not to interact with unexpected password prompts on untrusted sites reduces the UI-gesture trigger but is not a reliable control. Re-enable defaults once the fixed build is deployed.
