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 11 Jun 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 2026-10-26.

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 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 137.0.7151.103.

AI-suggested

To mitigate CVE-2025-5958, organizations should immediately update all Google Chrome installations to version 137.0.7151.103 or later, where the vulnerability has been patched. Beyond patching, implement strict web content filtering to block access to known malicious or untrusted websites. Employ browser security features such as sandboxing, site isolation, and strict content security policies to limit the impact of potential exploitation. Educate users about the risks of interacting with suspicious links or websites to reduce the likelihood of triggering the vulnerability. Monitor network and endpoint logs for unusual behavior indicative of heap corruption or exploitation attempts, such as crashes or unexpected process activity. Consider deploying endpoint detection and response (EDR) solutions capable of identifying exploitation techniques related to use-after-free vulnerabilities. Regularly review and update incident response plans to include scenarios involving browser-based remote code execution. Finally, maintain an inventory of browser versions in use across the organization to ensure timely patch management.

Description

Use after free in Media in Google Chrome prior to 137.0.7151.103 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Impact

The impact of CVE-2025-5958 is significant for organizations worldwide due to the widespread use of Google Chrome as a primary web browser. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain control over affected systems. This can result in data breaches, unauthorized access to sensitive information, installation of persistent malware, lateral movement within networks, and disruption of business operations. The vulnerability affects confidentiality by exposing private data, integrity by allowing unauthorized modifications, and availability by potentially crashing or destabilizing systems. Given that exploitation requires only user interaction with a malicious webpage, phishing campaigns or compromised websites can serve as vectors, increasing the risk of widespread attacks. Organizations with employees who frequently browse the internet, especially in sectors such as finance, government, healthcare, and critical infrastructure, face elevated risks. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the high severity score underscores the urgency of patching.
