Full Report
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Analysis Summary
# Vulnerability: Multiple Vulnerabilities in Google Chrome (April 2026)
## CVE Details
- **CVE ID:** CVE-2026-6296 through CVE-2026-6364 (Total of 34+ vulnerabilities)
- **CVSS Score:** Not explicitly provided, but rated as **High/Critical** severity by MS-ISAC.
- **CWE:** Multiple, primarily focusing on:
- **Use After Free** (CWE-416)
- **Heap Buffer Overflow** (CWE-122)
- **Type Confusion** (CWE-843)
- **Out of Bounds Read/Write** (CWE-125 / CWE-787)
## Affected Systems
- **Products:** Google Chrome Browser
- **Versions:**
- Windows and macOS: Versions prior to 147.0.7727.101/102
- Linux: Versions prior to 147.0.7727.101
- **Configurations:** All users are affected; impact is greatest for accounts with full administrative privileges.
## Vulnerability Description
Multiple security flaws exist within various Chrome components including **ANGLE, V8 (JavaScript engine), Skia (graphics), PDFium, and CSS**. The most severe issues are memory corruption vulnerabilities (Use After Free and Heap Buffer Overflows). If a user visits a specially crafted malicious website, an attacker can leverage these flaws to bypass security boundaries and execute arbitrary code on the underlying operating system.
## Exploitation
- **Status:** Not currently reported as exploited in the wild; no public PoC listed in the advisory.
- **Complexity:** Medium (requires user interaction/social engineering to visit a malicious URL).
- **Attack Vector:** Network (Remote/Drive-By Compromise).
## Impact
- **Confidentiality:** High (Attacker can view/access local data).
- **Integrity:** High (Attacker can change or delete data and install programs).
- **Availability:** High (Attacker can create new accounts or disrupt system access).
## Remediation
### Patches
Update Google Chrome to the following versions immediately:
- **Windows/macOS:** 147.0.7727.101/102
- **Linux:** 147.0.7727.101
### Workarounds
- **Principle of Least Privilege:** Operate the browser using a non-privileged user account to limit an attacker’s ability to modify system files or create new accounts.
- **Web Filtering:** Block access to known malicious domains to prevent drive-by downloads.
## Detection
- **Indicators of Compromise:** Browser crashes when visiting specific sites; unauthorized creation of local user accounts; suspicious unauthorized software installations.
- **Detection methods and tools:**
- Use automated vulnerability scanners to identify outdated Chrome installations.
- Monitor EDR logs for suspicious sub-processes spawned by `chrome.exe`.
