Google Chrome: Use-after-free in Transactions Platform
Summary
A use-after-free vulnerability in the Transactions Platform component of Google Chrome desktop allows a remote attacker to execute arbitrary code inside the browser sandbox. Exploitation requires that the victim loads a crafted HTML page, for example through phishing or a malicious link. According to the research notes, full compromise would normally require a second sandbox-escape vulnerability, but this is not confirmed by the sources.
Affected
- Google Chrome desktop versions prior to 156.0.8078.47
Fixed in
- Google Chrome 156.0.8078.47 or later (Windows, macOS and Linux)
- Later stable builds are available; the advisory for the 27 October stable update lists 156.0.8078.73 or later
- Chromium-based browsers such as Microsoft Edge and Linux distribution Chromium packages: fixed build numbers unknown
Workaround
No workaround documented. Install the security update.
Exploitation
- CVSS 3.1 base score 8.8 (High), vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation none, automatable no, technical impact total
- No evidence of exploitation in the wild found
- No public proof-of-concept found
Our recommendation
- Update Google Chrome on all endpoints to the latest stable build and verify the version numbers.
- Also update Microsoft Edge and any Chromium packages on Linux systems.
- Enable automatic browser updates or enforce them through update policies.
- Monitor for newer advisories and exploitation reports for this CVE.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
