1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the victim to actively load attacker-controlled web content in a vulnerable Chrome build prior to 154.0.8037.57 (UI:R - the user must visit/render the malicious page). No authentication or prior privileges are needed (PR:N), and the attack is network-delivered (AV:N) with low complexity (AC:L). The main limiting factors are the user-interaction requirement and that the impact is renderer-scoped (S:U), meaning a full system compromise would additionally need a sandbox escape not described here. Applies to default Chrome configurations - no non-default feature or setting is indicated. |
| Impact | CVSS 3.1 base score is 8.8 (High) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H - network-reachable, low attack complexity, no privileges, but requiring user interaction (visiting a malicious page). The CWE-843 type-confusion class in a renderer typically yields a memory-corruption primitive that maps to full C:H/I:H/A:H, consistent with a drive-by RCE-class flaw contained within the renderer sandbox (S:U, no scope change). No EPSS score is provided, there is no CISA KEV listing, and no public POC is identified, so all quantitative exploitation-probability signals are absent. This means the risk profile rests almost entirely on the CVSS vector and product ubiquity rather than confirmed exploitation. Weigh it as a genuine HIGH priority for patching because Chrome is ubiquitous and browser type-confusion bugs are a historically favored exploitation target, but note there is no evidence of active or automated exploitation at this time - treat it as high-value-to-patch rather than under-active-attack. Note also a conflict in the input Tags: it is labeled 'Information Disclosure', which contradicts the I:H/A:H integrity and availability impacts in the vendor CVSS vector; the memory-corruption RCE class is not a pure disclosure issue. |
| Exploit ScenarioDerived | An attacker hosts or compromises a web page containing crafted JavaScript/content that triggers the type confusion in a vulnerable Chrome renderer when the victim visits it. The confusion lets the attacker manipulate an object as an incompatible type, corrupting memory to gain arbitrary read/write and ultimately code execution within the renderer process. No public exploit code has been identified, and success requires the victim to load the malicious page (UI:R). |

Type confusion (CWE-843) in Google Chrome before 154.0.8037.57 lets remote attackers corrupt memory and potentially disclose information or execute code inside the renderer by having a victim load attacker-controlled web content. The bug is unauthenticated and network-delivered (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base score 8.8 High), but requires the user to visit or render a malicious page, and the assessed scope is unchanged (S:U), so renderer-scoped compromise would need a separate sandbox escape to reach full system impact; no public exploit identified at time of analysis, and no CISA KEV entry is associated with this CVE. Chrome ships on an aggressive release cadence, so the fix is already available in the stable channel and risk is concentrated in unpatched or auto-update-disabled fleets.
Earlier versions of this analysis (1)
Google Chrome desktop (stable channel) is affected by a security flaw addressed in the vendor's stable-channel update; because this record carries no description, CWE, vendor severity, or EPSS data, the exact weakness class and real-world impact cannot be confirmed from the available intelligence. The independently assessed vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) describes an unauthenticated, network-reachable attack that requires user interaction - the profile typical of a browser flaw where the victim must open attacker-influenced content - and would yield high confidentiality, integrity, and availability impact if successfully triggered. Exploitation status at time of analysis: no public exploit code identified, no CISA KEV entry, no EPSS probability available, and a vendor patch is available per the Chrome Releases advisory, so residual risk is concentrated in Chrome installations that have not yet updated.
RemediationAI
Vendor-released patch: 154.0.8037.57 - upgrade Google Chrome to 154.0.8037.57 or later via the stable-channel update described at http://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0856730748.html. On managed endpoints, force an update check and restart of the browser through your software-deployment or Chrome Browser Cloud Management tooling, since the fix only takes effect after the browser process is relaunched; verify the reported version in chrome://version rather than relying on a successfully delivered update package. Ubuntu and other Chromium-package distributions should confirm the 154.0.8037.57-equivalent package revision is installed from their own advisory channel, as the vendor:ubuntu attribution indicates this CVE is being tracked there as well. Where the update cannot be applied immediately, treat Chromium's renderer sandbox and Site Isolation as the primary blast-radius control and note the trade-offs plainly: Site Isolation and the sandbox reduce the likelihood that a renderer-scoped type-confusion primitive escalates to full system compromise but are not a substitute for the patch, and they carry performance/memory cost when enabled or strengthened. Blocking or restricting end-user web browsing to a curated allowlist is effective against drive-by delivery but degrades usability and is impractical for general user populations; disabling JavaScript or the affected rendering features is not a targeted workaround here because the specific vulnerable component is not publicly identified. Browser hardening flags that broadly restrict JIT or renderer behavior can raise exploitation cost but break legitimate web applications, so validate against business-critical sites before deployment.

Technical ContextAI · show details
CWE-843 (Type Confusion) is a memory-safety class in which an object allocated or interpreted as one type is later accessed as another; the mismatch lets an attacker control which fields are treated as pointers, lengths, or vtables, typically yielding out-of-bounds reads (matching the 'Information Disclosure' tag) or attacker-influenced writes (matching the 'Memory Corruption' tag) inside the affected process. In Chromium this class most commonly arises in the JavaScript engine, Blink, or a browser IPC component; the specific subcomponent is not disclosed in the available data, as Google's stable-channel advisories deliberately withhold component details until a majority of users have patched, and the linked Chromium issue (issues.chromium.org/issues/558764482) is the tracking record rather than a technical writeup. The provided CVSS vector AV:N/AC:L/PR:N/UI:R/S:U indicates the malicious input is delivered over the network from a remote origin, no credentials or prior foothold are needed, and no special complexity is required, but the victim must actively load the page, which is why user interaction is scored. No CPE strings were supplied with this record; the affected artifact is identified by version (Chrome stable builds below 154.0.8037.57) and by the Chrome Releases advisory rather than by a structured platform CPE.

Executive ViewAI
Google Chrome versions prior to 154.0.8037.57 contain a memory-corruption flaw that can be triggered when an employee simply browses to a crafted web page, potentially allowing an attacker to run code within the browser's renderer process on the affected endpoint. Because Chrome is widely deployed across the workforce and browsing hostile content is a routine business activity, unmanaged or auto-update-disabled installations represent the primary exposure. Leadership should care because a compromised renderer is a foothold on employee workstations, and while no public exploit has been observed to date, the vendor fix is already available and the remediation cost is low relative to the potential for data disclosure or further intrusion.
Apply vendor patch.
