Heap buffer overflow in CSS in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Google Chrome versions prior to 146.0.7680.153 contain a heap buffer overflow in CSS parsing that enables remote code execution when users visit malicious HTML pages. An unauthenticated attacker can trigger heap memory corruption through a crafted webpage, potentially achieving arbitrary code execution with user privileges. A patch is available and should be applied immediately to all affected systems.
Technical ContextAI
This vulnerability is a heap buffer overflow (CWE-122) occurring in Chrome's CSS parsing and rendering subsystem. Heap buffer overflows occur when a program writes data beyond the allocated boundaries of a heap-based buffer, potentially corrupting adjacent memory structures including heap metadata, function pointers, or other object data. In the context of CSS rendering, the overflow likely originates from improper bounds checking when processing malformed or adversarially crafted CSS properties, selectors, or values. The vulnerability is classified under CWE-122 (Heap-based Buffer Overflow), indicating memory corruption at the heap level rather than the stack. Chrome's rendering engine processes untrusted CSS from remote web pages, making this a natural attack surface for heap corruption exploitation.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later on all affected systems. The patch is available through Chrome's automatic update mechanism (Settings > About Google Chrome > Check for updates) and will be installed automatically upon browser restart. For enterprise environments using managed deployments, update Chromium via your OS package manager (apt/yum/brew) to the patched version. On Debian-based systems, update chromium-browser or google-chrome-stable packages to the latest available version addressing CVE-2026-4442. Ensure auto-update policies are enabled to mitigate future similar issues. Until patching is complete, isolate users from untrusted web content where possible, though this is impractical for general browsing—prioritize rapid patching instead.
