Google Chrome: Memory corruption in Network component allows sandbox code execution
Summary
Google Chrome prior to 156.0.8078.47 contains a memory corruption flaw in the Network component (CWE-119). A remote attacker can potentially execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The CVSS 3.1 base score is 8.8, but Chromium rates the issue as Low severity, and the description limits the impact to code execution inside the sandbox.
Affected
- Google Chrome prior to 156.0.8078.47 (Desktop)
- Chromium-based browsers that consume the affected Chromium code, such as Microsoft Edge, depend on their vendor's fixed builds (Edge: prior to 156.0.4314.42 according to a third-party bulletin, unverified)
Fixed in
- Google Chrome 156.0.8078.47 or later (newer stable builds are available and recommended)
- Debian DSA 6577-1 and DLA 4853-1 for Chromium
- Ubuntu: chromium-browser is a snap wrapper, check the snap channel
Workaround
- Unknown. No vendor-documented workaround was found; apply the update.
Exploitation
- No evidence of active exploitation found at the time of research.
- No public proof-of-concept found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Chrome and Edge to the newest stable build, at least 156.0.8078.47 (Edge: at least 156.0.4314.42 according to the bulletin, verify with Microsoft).
- Inventory all Chrome and Edge installations and check the version.
- Confirm that automatic updates are enabled.
- Re-check NVD and CISA KEV in one week.
