Google Chrome: Use-after-free in Animation allows code execution in sandbox
Summary
A use-after-free vulnerability in the Animation component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The victim must open a crafted HTML page, and no privileges are required. The sandbox is a separate protection layer, so this flaw alone does not give full control over the system.
Affected
- Google Chrome prior to 156.0.8078.47 (according to the NVD description)
- Conflicting third-party data: VulDB lists up to 155.0.8059.84. Not verified against the vendor advisory.
Fixed in
- Google Chrome 156.0.8078.47 or later for Windows, macOS and Linux, according to third-party reports
- Install the newest Stable build, as later Stable builds also exist.
Workaround
Unknown. No vendor workaround found. Installing the fixed build is the remedy.
Exploitation
- No evidence of in-the-wild exploitation found.
- No public proof-of-concept found. Status unknown rather than confirmed absent.
- A community tracker lists the CVE as not in CISA KEV. Not verified against the catalog.
Our recommendation
- Update Google Chrome on all workstations to the newest Stable build.
- Verify the version on managed devices, including pinned devices or devices with disabled updates.
- Check Chromium-based products (Edge, Brave, etc.) and Linux distribution packages separately against their own advisories.
- Prioritise workstations used for web browsing.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
