Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in the SVG component of Google Chrome versions before 154.0.8037.97. A use-after-free occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution. An attacker could exploit this by crafting a malicious HTML page to trigger the flaw.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 154.0.8037.97. To detect it, check your Chrome version by running chrome --version or chrome://version in the browser. If your version is below 154.0.8037.97, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your system. Since it occurs in the sandboxed environment of Chrome, the attacker would gain control within the sandbox, potentially accessing sensitive data or performing unauthorized actions.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's SVG handling that could allow remote code execution inside the sandbox. Such vulnerabilities may lead to unauthorized data access or modification, which could violate GDPR's integrity and confidentiality principles or HIPAA's safeguards for protected health information. However, specific compliance impacts depend on deployment context and mitigations.

Mitigation Strategies

Update Google Chrome to version 154.0.8037.97 or later to address the use after free vulnerability in SVG rendering.
