Vulnerability Details
The official description of CVE-2025-0762 notes that there is a use-after-free vulnerability in DevTools in Google Chrome prior to version 132.0.6834.159. This vulnerability is classified under CWE-416, indicating improper handling of memory management. The publication date of the vulnerability was January 29, 2025, illustrating the importance of timely updates and patches.
The vulnerability has a CVSS score of 8.8, which is categorized as high severity. The details of the CVSS vector indicate the attack vector is network-based (AV:N), with low attack complexity (AC:L), requiring no privileges (PR:N) but user interaction (UI:R). The impacts on confidentiality, integrity, and availability are all rated high (C:H, I:H, A:H).
Technical Analysis
The root cause of this vulnerability is linked to improper memory management, specifically a use-after-free condition in the DevTools. This flaw allows an attacker to manipulate heap memory, potentially leading to arbitrary code execution or data corruption. The attack vector is network-based, and while user interaction is required, the complexity of the attack is considered low, making it more accessible for attackers.
In terms of privileges required, no prior privileges are necessary for exploitation, which means any user can be targeted. The vulnerability significantly impacts confidentiality, integrity, and availability, potentially allowing attackers to read sensitive information, modify data, or crash the application.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-0762 is substantial. Given the widespread usage of Google Chrome and its role in accessing sensitive web applications, the potential blast radius is significant. Attackers may leverage this vulnerability to gain unauthorized access to a user's system, leading to data breaches or system compromise.
Organizations should assess their exposure to this vulnerability based on their usage of affected versions of Google Chrome and prioritize remediation efforts accordingly. The urgency of addressing this vulnerability is critical, as failure to do so could result in significant operational and reputational damage.
