Update Chrome to patch critical browser security flaws

Google released a Chrome security update (stable channel 149.0.7827.196/197) that patches 18 vulnerabilities, including two Critical WebGL use-after-free bugs that could allow an attacker to escape the browser sandbox via a crafted HTML page; there is no indication these particular CVEs are being actively exploited. The advisory includes version numbers, manual update instructions, and contextual notes about the risk of chaining browser sandbox escapes with other web-based vulnerabilities.
