MITRE ATT&CK
2 techniques across 2 tactics: Execution, Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires a victim using Chrome prior to 156.0.8078.47 to open an attacker-crafted HTML page (UI:R, user interaction mandatory) - this is the primary limiting factor, as no exploitation occurs without the victim navigating to malicious content. No authentication is required (PR:N) and no non-default configuration or special feature toggle is named in the description; the UAF resides in the Turbolev component and is reachable against default Chrome. The key factor that LIMITS real-world impact is that successful code execution is confined to the renderer sandbox, so attaining full host compromise additionally requires chaining a separate sandbox-escape vulnerability not covered by this CVE. |
| Impact | This is a genuine priority for any environment running Google Chrome, but with an important nuance that tempers the headline CVSS 8.8. The CVSS vector (AV:N/AC:L/PR:N/UI:R) describes a remote, low-complexity, unauthenticated attack requiring only that a victim open a crafted HTML page - a trivially achievable condition for a browser. However, the description explicitly states code execution occurs 'inside the sandbox,' meaning the impact (C:H/I:H/A:H, S:U) is confined to the compromised renderer process; full host compromise would require chaining a separate sandbox-escape bug, which this CVE does not provide. Chromium rates the severity 'High' (not Critical), consistent with a sandboxed-renderer UAF. On the exploitation-signal side there is NO conflict to resolve because the data is simply absent: no CISA KEV listing, no EPSS score, and no POC are provided in the input, so there is no public exploit identified at time of analysis. The SSVC/automatable and EPSS dimensions cannot be evaluated from the given data. Net assessment: patch promptly because the product is ubiquitous and the memory-corruption bug class is reliably weaponizable by sophisticated actors, but in the absence of KEV/POC/EPSS signals this is a proactive-hygiene priority rather than a confirmed active-exploitation emergency. |
| Exploit ScenarioDerived | A remote attacker hosts or compromises a web page containing malicious HTML that triggers the use-after-free in the Turbolev component. When a victim running a vulnerable Chrome build (prior to 156.0.8078.47) visits the page, the freed object is reclaimed with attacker-controlled data, yielding arbitrary code execution within the renderer sandbox. Because the flaw is low-complexity and needs only a page visit, it is well suited to watering-hole or malvertising delivery, though no public exploit is identified at time of analysis and full system compromise would require an additional sandbox escape. |

Alert meAnalysisAIv1 – Oct 21, 2026
Arbitrary code execution inside the Chrome renderer sandbox is possible in Google Chrome versions prior to 156.0.8078.47 due to a use-after-free in the Turbolev component. A remote attacker can trigger it only when a victim opens a crafted HTML page (UI:R, PR:N), and the resulting code execution is confined to the sandbox, so full host compromise would require a separate sandbox escape. No public exploit was identified at time of analysis, and Google has released Chrome 156.0.8078.47 to address it.
RemediationAI
Vendor-released patch: upgrade Google Chrome to 156.0.8078.47 or later. Review the Chrome desktop stable-channel advisory at https://chromereleases.googleblog.com/2026/10/stable-channel-update-for-desktop_02018666648.html and the Chromium issue at https://issues.chromium.org/issues/570003644; if ChromeOS is in scope, review the related ChromeOS stable-channel advisory at http://chromereleases.googleblog.com/2026/10/stable-channel-update-for-chromeos_01150416531.html. Until updates are deployed, reduce exposure by preventing users from opening untrusted HTML pages or links, since exploitation requires the victim to navigate to attacker-controlled content (UI:R), and enforce browser update policies; these controls lower likelihood but do not fix the use-after-free, and the Chrome sandbox limits code execution to the renderer rather than substituting for patching.

Technical ContextAI · show details
CVE-2026-113019 is a CWE-416 use-after-free in Google Chrome's Turbolev component. The CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H vector indicates network reachability, low attack complexity, no authentication requirement, mandatory user interaction, and high confidentiality, integrity, and availability impact within the vulnerable component's security scope. In Chrome's multi-process architecture, the renderer is sandboxed; a crafted HTML page can trigger reuse of freed memory in Turbolev and allow arbitrary code execution inside that sandbox, but not direct host compromise. The supplied tags classify the issue as RCE, denial of service, memory corruption, and use-after-free. EUVD affected-version data identifies Chrome builds below 156.0.8078.47 as vulnerable; no CPE strings were provided in the input.

Web-delivered UAF needs no auth (PR:N) but requires the victim to open a page (UI:R); execution stays within the renderer sandbox so scope is unchanged (S:U) with high C/I/A.

Lifecycle Timeline

Use after free in Turbolev in Google Chrome prior to 156.0.8078.47 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)
Executive ViewAI
Google Chrome endpoints running versions below 156.0.8078.47 are exposed to a high-severity code-execution weakness that could allow a malicious webpage to run code inside the browser's protected renderer environment. The operational exposure is broad because Chrome is widely deployed, but required user interaction and sandbox containment reduce the likelihood of immediate full-device compromise; no public exploit identified at time of analysis. Leadership should prioritize fleet-wide patching to prevent ordinary web browsing from becoming an initial foothold for follow-on attacks.

What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
