Analysis

Impact

Use‑after‑free in the V8 JavaScript engine (CWE‑416) in Google Chrome versions prior to 150.0.7871.46 allows a remote attacker to execute arbitrary code inside the renderer’s sandbox by delivering a crafted HTML page.

Affected Systems

Any Chrome deployment that includes the vulnerable V8 build before version 150.0.7871.46 is affected. The affected builds are part of Chrome’s stable channel and are present on all platforms supported by Chrome.

Risk and Exploitability

The CVSS score of 8.8 classifies this flaw as high severity. The EPSS score is below 1 %, showing a very low probability of exploitation in the wild, and the vulnerability is not listed in CISA’s KEV catalog. The attack vector is remote; a malicious web page or content delivered to the user can trigger the exploit, but successful exploitation remains limited to code execution within the renderer sandbox.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
