CVE-2026-5860: Use after free in Google Chrome
Use after free in WebRTC in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability is a use-after-free issue (CWE-416) in the WebRTC implementation of Google Chrome versions before 147.0.7727.55. Exploitation requires user interaction (UI:R) and can be triggered remotely over the network (AV:N) without privileges (PR:N). Successful exploitation can lead to arbitrary code execution inside the sandbox, impacting confidentiality, integrity, and availability. The CVSS vector indicates low attack complexity and high impact. The vendor advisory is available but does not explicitly state patch status.
Potential Impact
If exploited, an attacker could execute arbitrary code within the sandboxed environment of Chrome, potentially compromising user data and browser integrity. The vulnerability affects confidentiality, integrity, and availability with high severity. No known active exploits have been reported so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop.html for current remediation guidance.
