Google Chrome: Use-after-free in Track component allows code execution
Summary
A use-after-free vulnerability (CWE-416) in the Track component of Google Chrome before 155.0.8059.39 can be exploited remotely. An attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The attack needs no authentication but requires that the user loads the page. The CVSS base score is 8.8 (High).
Affected
- Google Chrome (desktop) prior to 155.0.8059.39
- Chromium packages in Linux distributions prior to the fixed builds listed below
- Microsoft Edge: the fixed Edge build could not be verified; check Microsoft's release notes
Fixed in
- Google Chrome 155.0.8059.39 (Linux)
- Google Chrome 155.0.8059.39/.40 (Windows and macOS, according to the research notes; verify on the Chrome Releases post, as one third-party source contradicts this)
- Debian bookworm chromium 155.0.8059.39-1~deb12u1
- Chainguard Wolfi chromium 155.0.8059.39-r0
- SUSE / openSUSE chromium 155.0.8059.39
Workaround
No workaround documented. Update Chrome and restart the browser.
Exploitation
- No known exploitation in the wild at the time of writing.
- Not listed in CISA KEV. CISA SSVC data lists exploitation as none and automatable as no.
- No public proof of concept found; this does not prove that none exists.
Our recommendation
- Check the Chrome version on every endpoint and confirm it is 155.0.8059.39 or later (or the matching Chromium package version on Linux).
- Force a browser update and restart Chrome and other Chromium-based browsers.
- Patch within your normal critical browser update window, prioritising workstations with web browsing exposure.
- Check whether a phased rollout has left some machines without the fixed build.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
