Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Google Chrome to 141.0.7390.107.

AI-suggested

To mitigate CVE-2025-11756, organizations should immediately update all Chrome installations to version 141.0.7390.107 or later where the vulnerability is patched. Beyond patching, organizations should implement strict browser security policies, including disabling or restricting JavaScript execution on untrusted sites using Content Security Policy (CSP). Employing browser isolation technologies can limit the impact of compromised renderer processes. Network-level protections such as web filtering and Safe Browsing enhancements should be maintained and updated. User awareness training to avoid interacting with suspicious links or sites can reduce exploitation likelihood. Monitoring for unusual browser behavior or crashes may help detect exploitation attempts. Finally, applying defense-in-depth strategies, including endpoint detection and response (EDR) tools, can help identify and contain any successful attacks leveraging this vulnerability.

Description

Use after free in Safe Browsing in Google Chrome prior to 141.0.7390.107 allowed a remote attacker who had compromised the renderer process to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity: High)

Impact

The exploitation of CVE-2025-11756 can lead to severe consequences for organizations worldwide. Successful exploitation may allow attackers to execute arbitrary code within the browser, potentially leading to full system compromise if sandbox escapes are chained. Confidential information accessed through the browser, such as credentials, session tokens, and sensitive data, could be exposed or manipulated. Integrity of data processed or displayed by the browser may be compromised, and availability could be affected if the exploit causes crashes or denial of service. Given Chrome's dominant market share in enterprise and consumer environments, a large number of users and organizations are at risk. Attackers could leverage this vulnerability for targeted espionage, data theft, or as an initial foothold in a network. The requirement for user interaction limits automated mass exploitation but does not eliminate risk, especially in spear-phishing or watering hole attacks.
