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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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 Chrome and google/chrome to 149.0.7827.53.

AI-suggested

The vendor advisory linked does not explicitly confirm a patch or remediation level. The affected version is prior to 149.0.7827.53, which suggests that updating to version 149.0.7827.53 or later may address the issue.

Description

CVE-2026-11075 is an out-of-bounds read vulnerability in the V8 JavaScript engine used by Google Chrome. It affects versions prior to 149.0.7827.53 and allows a remote attacker to read potentially sensitive information from process memory via a crafted HTML page. The vulnerability has a medium severity rating with a CVSS score of 6.5. No known exploits are reported in the wild. A vendor advisory is available but does not explicitly confirm patch availability or remediation status.

Impact

Successful exploitation can lead to disclosure of sensitive information from the browser's memory space. There is no indication of impact on integrity or availability. No known active exploits have been reported, reducing immediate risk.

Summary

This vulnerability involves an out-of-bounds read in the V8 engine component of Google Chrome before version 149.0.7827.53. An attacker can exploit this flaw by delivering a crafted HTML page that triggers the out-of-bounds read, potentially exposing sensitive information from the browser's process memory. The issue is classified under CWE-125 (Out-of-bounds Read). The CVSS 3.1 vector indicates the attack requires network access, no privileges, user interaction, and impacts confidentiality with high severity but does not affect integrity or availability.

The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
