Chrome 151 addresses 370 vulnerabilities, including seven critical-severity bugs such as use-after-free vulnerabilities in Compositing, Views, Skia, and Ozone; insufficient validation of untrusted input in Dawn and ANGLE; and a critical race condition in Updater. Over a dozen high-severity use-after-free bugs affect components like Navigation, V8, Loader, Autofill, and Media. Other high-severity issues include inappropriate implementation, insufficient policy enforcement, uninitialized use, integer overflow, out-of-bounds read/write, type confusion, policy bypass, race conditions, object lifecycle issues, and cryptographic flaws. The update also fixes 170 medium- and 122 low-severity defects. Thirty vulnerabilities impact ANGLE, the WebGL backend. Google discovered 349 of these defects internally and credited external researchers for 21, paying $58,500 in bug bounties. The update is available for Windows, macOS, and Linux.

The vulnerabilities fixed in Chrome 151 include multiple critical and high-severity issues that could potentially allow memory corruption, improper input validation, race conditions, and other security weaknesses. These could impact browser stability, security, and potentially enable exploitation if left unpatched. The update mitigates risks associated with these vulnerabilities by addressing them comprehensively. No known exploits in the wild have been reported at the time of this release.

A fix is available in Chrome version 151.0.7922.71/.72 for Windows, macOS, and Linux. Users and organizations should update to this version promptly to mitigate the addressed vulnerabilities. Since this is a client software update, applying the official Chrome update is the recommended remediation. No additional vendor advisories indicate further required actions.
