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: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

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 141.0.7390.54.

AI-suggested

European organizations should prioritize updating all instances of Google Chrome to version 141.0.7390.54 or later as soon as possible to remediate this vulnerability. Network-level protections such as web filtering and blocking access to known malicious or untrusted websites can reduce exposure. Employing endpoint detection and response (EDR) solutions with behavioral analytics may help identify anomalous browser activity indicative of exploitation attempts. Security awareness training should emphasize caution when visiting unknown or suspicious websites, even though no user interaction is required for exploitation. Organizations should also monitor threat intelligence feeds for any emerging exploit code or attack campaigns related to CVE-2025-11211. Implementing Content Security Policy (CSP) headers and sandboxing browser tabs can provide additional layers of defense. Regular vulnerability scanning and patch management processes must be enforced to ensure timely updates. Finally, consider isolating high-risk browsing activities or using dedicated browsers for sensitive tasks to limit potential exposure.

Description

Out of bounds read in Media in Google Chrome prior to 141.0.7390.54 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity: Medium)

Impact

For European organizations, this vulnerability poses a significant risk of confidential data leakage through memory disclosure when users browse malicious websites. Since Chrome is widely used across Europe in both enterprise and consumer environments, the potential attack surface is large. Sensitive information such as authentication tokens, personal data, or corporate secrets stored in browser memory could be exposed. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach can facilitate further attacks like session hijacking or targeted phishing. The lack of required privileges or user interaction increases the risk of automated exploitation campaigns. Critical sectors such as finance, healthcare, and government agencies in Europe could be targeted due to the value of the information accessible via browser memory. The impact on integrity and availability is negligible, but the confidentiality impact alone justifies urgent mitigation. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially given the public disclosure.
