Chrome: Access of Resource Using Incompatible Type

CVE-2024-2887 is a high-severity access of resource using incompatible type vulnerability in Chrome from Google, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 123.0.6312.86 as the first without the flaw, so updating Chrome to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 17.9% chance of exploitation within 30 days, which is in the top 2.77% of all scored CVEs.

Patch this week

EPSS places it among the vulnerabilities most likely to be exploited soon.

What to do

  1. Update Chrome to 123.0.6312.86 or a later version.
  2. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Access of Resource Using Incompatible Type
