CVE-2026-110170: 
Google Chrome vulnerability analysis and mitigation

CVE-2026-110170 is a Use After Free vulnerability in the Bindings component of Google Chrome that allows a remote attacker to read memory inside the browser sandbox via a crafted HTML page. It affects Google Chrome versions prior to 155.0.8059.79 and was reported to Google on 2026-03-25, with a patch released on 2026-10-13. The vulnerability is rated High severity by the Chromium security team (Chrome Releases, GitHub Advisory).

The vulnerability is classified as CWE-416 (Use After Free), occurring in Chrome's Bindings component — the layer responsible for bridging JavaScript and native browser APIs. When memory associated with a binding object is freed but a reference to it is retained, a remote attacker can craft an HTML page that triggers access to the freed memory region, enabling reads within the sandbox. The Chromium issue tracker references bug ID 496308073, though full details remain restricted pending broad user update (Chrome Releases, GitHub Advisory).

Successful exploitation allows a remote attacker to read memory contents inside the Chrome sandbox via a malicious web page, potentially exposing sensitive in-process data such as credentials, session tokens, or other browser-held information. While the impact is constrained to sandbox memory reads (not full sandbox escape), this class of vulnerability can serve as a stepping stone in multi-stage exploit chains targeting full system compromise. Confidentiality is the primary concern; integrity and availability are not directly impacted by this specific flaw (Chrome Releases, Red Hat Bugzilla).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for CVE-2026-110170 as of the disclosure date. The EPSS score is listed at 0.0, and the vulnerability does not appear in the CISA Known Exploited Vulnerabilities catalog. Exploitation requires luring a victim to a crafted HTML page, making it a user-interaction-dependent attack vector (GitHub Advisory, Feedly).

1. Craft malicious HTML page: Develop an HTML page that manipulates Chrome's Bindings layer to trigger a use-after-free condition — for example, by creating and destroying binding objects in a specific sequence that leaves a dangling reference.
2. Host the page: Deploy the crafted page on an attacker-controlled web server or inject it via a compromised/malicious advertisement network.
3. Lure the victim: Social-engineer the target into visiting the malicious URL using phishing, malvertising, or a watering hole attack targeting Chrome users on versions prior to 155.0.8059.79.
4. Trigger memory read: When the victim's browser processes the page, the use-after-free is triggered, allowing the attacker to read memory contents within the Chrome sandbox.
5. Exfiltrate data: Use JavaScript or other browser APIs to transmit the read memory contents (e.g., tokens, credentials) back to the attacker's server (Chrome Releases, GitHub Advisory).

Google has released Chrome version 155.0.8059.79 (Linux) and 155.0.8059.79/.80 (Windows/Mac) which addresses this vulnerability. Users and administrators should update Chrome to version 155.0.8059.79 or later immediately. An Extended Stable channel update was also released to address this issue. No configuration-based workaround is available; upgrading is the only remediation (Chrome Releases).

Red Hat opened a tracking bug (Bug 2551941) for the vulnerability in the context of the Chromium browser package, classifying it as high priority and high severity. No notable independent researcher commentary or significant social media discussion has been identified beyond standard vulnerability tracking activity (Red Hat Bugzilla).
