Type confusion in V8 in Google Chrome prior to 99.0.4844.84 allowed a remote attacker to potentially exploit heap corruption via a crafted H

Noroxi assessment

Priority: This week (action score 72/100)

  • CISA has confirmed exploitation in the wild (Mar 28, 2022). Remediation deadline for US federal agencies: Apr 18, 2022.
  • Probability of exploitation in the next 30 days: 24.7% (FIRST EPSS); higher than 97.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: chromium (Debian:11) 99.0.4844.84-1~deb11u1; chromium (Debian:12) 99.0.4844.84-1; chromium (openSUSE:Tumbleweed) 99.0.4844.84-1.1.
  • Mentioned 6 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to chromium (Debian:11) 99.0.4844.84-1~deb11u1; chromium (Debian:12) 99.0.4844.84-1; chromium (openSUSE:Tumbleweed) 99.0.4844.84-1.1 or later.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
