CVE-2024-4671 is a security flaw in Chrome and other Chromium browsers, the open-source browser that Chrome, Edge, Brave and Opera are built on. Attackers can get past a security protection in Chrome and other Chromium browsers. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 13 May 2024.[1]

Chrome and other Chromium browsers is in things households have, such as phones, computers, browsers and everyday apps, so the fix matters at home as much as at work. Fixed in version 124.0.6367.201.

CISA calls it a visuals use-after-free in Google Chromium. In its words: “Google Chromium Visuals contains a use-after-free vulnerability that allows a remote attacker to exploit heap corruption via a crafted HTML page. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.”[1]

The underlying weakness is use after free (CWE-416), in MITRE’s list of common software weaknesses.[2]

It scores 9.6 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 13 May 2024. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 3 Jun 2024 to fix it.[1]

FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 8%. That’s in the top 6% of the flaws it scores.[4]

CISA assesses it as not automatable: each attack takes some work.

CISA doesn’t say who was attacked, or how.

Fix

Google has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]

  1. Update Chrome and other Chromium browsers now.Chrome updates itself, but only finishes when you restart it: open the menu, choose Help, then About Google Chrome, and click Relaunch. Edge, Brave, Opera and Vivaldi need the same. Then turn on automatic updates, so the next fix arrives on its own.
  2. Check you’re on 124.0.6367.201 or later.Fixed in version 124.0.6367.201. Anything older is what attackers are going after.
  3. If there’s no update, stop using it.CISA’s advice when a flaw being used in attacks has no fix is to stop using the product until it does.
