Google released a Chrome 149 security update that fixes 18 serious browser flaws affecting Windows, macOS, and Linux users. The batch includes four critical and 14 high-severity vulnerabilities in Chrome 149.0.7827.196/197 for Windows and macOS and 149.0.7827.196 for Linux; more than half are use-after-free memory-corruption bugs that can potentially lead to remote code execution, alongside out-of-bounds read, uninitialized use, insufficient validation of untrusted input, and implementation flaws. Google said none are known to be exploited in the wild.
Why it matters: Chrome is widely used, so browser security fixes can quickly affect large numbers of people and organizations. Users and IT teams should update Chrome promptly because several of the patched bugs could potentially let attackers run code through a malicious webpage.
