EXECUTIVE SUMMARY:
A critical security update addresses eighteen security vulnerabilities, including four rated critical and fourteen rated high severity. Several of these flaws could allow remote threat actors to execute arbitrary code or hijack execution flow on targeted systems. The core risks involve memory corruption issues, specifically use-after-free conditions and out-of-bounds reads across core browser components. These defects collectively expand the attack surface, creating opportunities for privilege escalation and system compromise. Immediate patching is recommended to secure endpoints against potential exploitation. CVE-2026-13028:This critical use-after-free vulnerability resides in the graphics rendering engine. An attacker could leverage this defect to reference memory after it has been freed, potentially hijacking the browser execution flow. Successful exploitation risks complete system compromise via unauthorized arbitrary code execution. With a CVSS score of 9.8, this vulnerability is considered critical because it can be exploited remotely without requiring user privileges and may result in full system compromise.[/subscribe_to_unlock_form]

- CVE-2026-13032: This critical vulnerability involves a use-after-free flaw within the web graphics processing subcomponent. Exploitation relies on improper memory management handling, enabling threat actors to execute arbitrary code. The risk remains high due to the component handling complex visual rendering tasks directly. The CVSS score of 9.8 reflects the high likelihood of remote exploitation and the potential for complete compromise of affected systems.
- CVE-2026-13033: This critical defect introduces an out-of-bounds read vulnerability within the browser core rendering framework component. Attackers can exploit this to read sensitive data outside allocated memory boundaries. This issue threatens data confidentiality and can lead to subsequent system destabilization. Its CVSS score of 9.1 indicates a severe security risk due to the possibility of exposing sensitive information and facilitating further attacks.
- CVE-2026-13038: This critical use-after-free vulnerability impacts the automated form filling subsystem. By exploiting the way memory states are retained, threat actors can inject and execute malicious code. The targeted component handles user data inputs, elevating the risk of credential exposure. The CVSS score of 9.8 highlights the vulnerability's ability to enable remote code execution with significant impact on confidentiality, integrity, and availability.
- CVE-2026-13021:This high-severity vulnerability involves an inappropriate implementation defect within the device-bound session credential component. Exploitation can undermine session integrity controls, potentially allowing session hijacking. It poses a significant risk to user authentication frameworks. A CVSS score of 8.8 indicates a high-risk issue capable of compromising user sessions and authentication mechanisms.
- CVE-2026-13022:This high-severity flaw stems from an inappropriate implementation within the automated form filling subsystem. Attackers can exploit this logic flaw to manipulate input processing. The vulnerability leads to data exposure or unauthorized configuration alterations. The CVSS score of 8.8 reflects the substantial impact this flaw can have on data integrity and user privacy.
- CVE-2026-13023:This high-severity vulnerability is caused by an uninitialized use flaw inside the graphics processing unit subsystem. Threat actors can exploit the undefined memory states to cause system instability or leak data. This creates a predictable vector for broader system compromise. Its CVSS score of 8.1 represents a significant security concern due to the possibility of information disclosure and application instability.
- CVE-2026-13024:This high-severity flaw is characterized by insufficient input validation in the web navigation subsystem. Attackers can bypass standard traffic filters by supplying malformed navigation strings. This risks unauthorized cross-origin navigation actions or data handling errors. The CVSS score of 8.1 reflects the potential for attackers to manipulate browser behavior and access restricted resources.
- CVE-2026-13025:This high-severity vulnerability presents insufficient input validation within the integrated developer tools subsystem. Malicious actors could exploit this validation gap to execute unauthorized commands inside the testing interface. The exploitation risk includes local sandbox escapes. A CVSS score of 8.8 highlights the significant impact that successful exploitation could have on browser security controls.
- CVE-2026-13026:This high-severity use-after-free vulnerability affects the digital identity credentials framework. Attackers can manipulate memory reference lifecycles during credential processing requests to execute arbitrary code. This poses a direct threat to identity verification integrity. The CVSS score of 8.8 indicates a serious risk of unauthorized code execution and credential compromise.
- CVE-2026-13027:This high-severity flaw involves a use-after-free vulnerability within the file system abstraction layer. Exploitation enables threat actors to execute code by forcing the browser to call unallocated memory locations. This introduces significant risks regarding local file tampering. Its CVSS score of 8.8 reflects the possibility of arbitrary code execution and unauthorized access to local resources.
- CVE-2026-13029:This high-severity use-after-free bug resides within the web authentication core component. Threat actors can disrupt memory references during authentication processes to bypass standard security restrictions. This elevates the risk of unauthorized account access. The CVSS score of 8.8 demonstrates the serious impact this vulnerability may have on authentication security.
- CVE-2026-13030:This high-severity defect stems from an uninitialized use vulnerability in the graphics processing unit subsystem. Attackers can exploit uninitialized memory variables to generate unexpected behavior or extract systemic data. This weakens overall memory isolation barriers. A CVSS score of 8.1 signifies a high-risk vulnerability that can expose sensitive information and affect system reliability.
- CVE-2026-13031:This high-severity use-after-free flaw exists within the core rendering engine architecture.
