Key insight
Pure patch information: there is no indication of active exploitation, no PoC, and no named attackers , the only value lies in promptly updating Chrome and Chromium-based browsers.
Description
In Google Chrome prior to version 157.0.8103.78, a type confusion exists in the V8 JavaScript compiler, rated Chromium severity "High" by Google. A crafted HTML page is sufficient for a remote attacker to execute arbitrary code inside the browser sandbox; an additional sandbox escape vulnerability would be required for full host compromise. All Chrome installations below the stated version are affected, as are derived Chromium-based browsers that have not yet adopted the patch level. At the time of the NVD publication, there is no information on exploitation in the wild, no public exploit, and no attribution to an attacker group.
