CVE-2024-2887· NVD / CVE Program· CNA Chrome

Type Confusion in WebAssembly in Google Chrome prior to 123.0.6312.86 allowed a remote attacker to execute arbitrary code via a crafted HTML

Noroxi assessment

Priority: Monitor (action score 35/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 17.9% (FIRST EPSS); higher than 97.1% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: chromium (Debian:12) 123.0.6312.86-1~deb12u1; chromium (Debian:13) 123.0.6312.86-1; opera (openSUSE:Leap 15.6 NonFree) 109.0.5097.45-lp156.2.3.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to chromium (Debian:12) 123.0.6312.86-1~deb12u1; chromium (Debian:13) 123.0.6312.86-1; opera (openSUSE:Leap 15.6 NonFree) 109.0.5097.45-lp156.2.3.1 or later.
