Integrity: None
Availability: None

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.

Exploitation evidence

Disclosed: evidence found.
CVE published 20 May 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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

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 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 Google Chrome to 148.0.7778.179.

AI-suggested

Google has published a vendor advisory linked in the data, but it does not explicitly state the patch or remediation status. The affected versions are prior to 148.0.7778.179, implying that updating to version 148.0.7778.179 or later likely addresses the issue.

Description

CVE-2026-9122 is a medium severity vulnerability in Google Chrome on Mac platforms prior to version 148.0.7778.179. It involves an out of bounds read in the GPU component, which could allow a remote attacker to obtain potentially sensitive information from process memory by delivering a crafted HTML page. The vulnerability does not affect integrity or availability but impacts confidentiality. There are no known exploits in the wild at this time. A vendor advisory is available but does not explicitly confirm patch status or remediation details.

Impact

Successful exploitation allows a remote attacker to obtain potentially sensitive information from the memory of the GPU process in Chrome on Mac. There is no impact on integrity or availability. No known exploits have been reported in the wild.

Summary

This vulnerability is an out of bounds read in the GPU subsystem of Google Chrome on Mac systems before version 148.0.7778.179. An attacker can exploit this by crafting a malicious HTML page that, when rendered by the browser, causes the GPU process to read memory outside its intended bounds. This can lead to disclosure of sensitive information from process memory. The CVSS score is 6.5, reflecting a network attack vector with low complexity, no privileges required, user interaction needed, and a high impact on confidentiality only.
