| Exploitation Conditions | Exploitation requires a victim running Google Chrome before 156.0.8078.73 to load attacker-controlled content - the CVSS UI:R and the description's 'via a crafted HTML page' confirm user interaction (visiting or being served a malicious page) is the gating condition; no authentication is required (PR:N) and default configurations are affected. The scope change (S:C) and 'outside the sandbox' wording indicate successful exploitation breaks out of Chrome's renderer sandbox to the host. The principal limiting factor is the required user interaction (loading the crafted page) and the version boundary: patched builds (156.0.8078.73 and later) are not affected. The exact memory-corruption trigger inside Skia is not detailed in the available sources. |
| Impact | Signals mostly align toward high priority but with one notable tension. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H, 9.6 Critical) describes a network-reachable, low-complexity, unauthenticated flaw requiring only that a victim load a crafted HTML page, with a scope change reflecting that code executes outside the Chrome sandbox - i.e. a full renderer-to-host compromise. The vuln.today Decision label is act_now and a vendor patch is available, reinforcing urgency. However, the EPSS score is only 0.22% (13th percentile) and the vulnerability is NOT listed in CISA KEV, so there is no public evidence of active exploitation; the input shows no verified exploit code either. The act_now label therefore appears driven by the vulnerability's intrinsic severity (unauthenticated sandbox-escape RCE in a ubiquitous browser) and patch availability rather than by observed exploitation. This is a genuine priority for patch deployment, but defenders should read it as 'pre-emptive, patch-now' rather than 'under mass exploitation': the low EPSS and absent KEV listing indicate no confirmed widespread exploitation at time of analysis. No SSVC component values (automatable, technical impact) were supplied beyond the aggregate act_now label. |
| Exploit ScenarioDerived | An attacker hosts or compromises a web page containing malformed graphics content that triggers the memory-corruption flaw in Chrome's Skia rendering engine. When a victim using a pre-156.0.8078.73 build simply visits the page, the corruption is leveraged to execute arbitrary code outside the browser sandbox on the host. No public, verified exploit code is identified in the provided data, so this scenario is inferred from the CVSS vector and description. |

Alert meAnalysisAIv1 – Oct 28, 2026
Memory corruption in the Skia graphics component of Google Chrome before 156.0.8078.73 can let a remote attacker execute arbitrary code outside the browser sandbox when a victim loads a crafted HTML page, making this a sandbox-escape-class remote code execution issue (CVSS 9.6, scope changed, C/I/A all High). No authentication is required, but exploitation is gated on user interaction - the victim must visit or be served the malicious page - and only unpatched builds are exposed, since 156.0.8078.73 and later are fixed by the vendor. Exploitation status is currently quiet: there is no CISA KEV listing and no public exploit identified at time of analysis, while EPSS sits at 0.22% (13th percentile), yet the vuln.today decision label is act_now, driven by the severity and sandbox-escape potential rather than observed activity.
RemediationAI
Vendor-released patch: 156.0.8078.73 - upgrade Google Chrome to 156.0.8078.73 or later from the Stable Channel advisory at https://chromereleases.googleblog.com/2026/10/stable-channel-update-for-desktop_0562499947.html and confirm the installed version through Chrome's About/Settings version display, then relaunch the browser so the new binary is actually in use rather than a pending update. Chrome's background updater normally stages this build automatically, but endpoints with pinned versions, frozen update policies or managed fleets should be pushed to 156.0.8078.73 explicitly; the supplied evidence lists no interim workaround, no mitigation flag and no configuration change, so updating is the only documented fix, and version-gating or blocking of untrusted HTML is not described as a control in the available sources. The Chromium issue (https://issues.chromium.org/issues/568936530) can be tracked for any follow-up detail, and because this is a sandbox-escaping memory-corruption bug, prioritize the update on machines whose users routinely browse untrusted or attacker-influenced web content.

Technical ContextAI · show details
Skia is the open-source 2D graphics engine embedded in Chromium and Google Chrome, responsible for rasterizing and compositing everything the renderer paints - page content, SVG, canvas, images and fonts - which makes attacker-supplied web content reach it directly during normal browsing. The flaw is classified CWE-119 (improper restriction of operations within the bounds of a memory buffer), i.e. a buffer/memory-corruption condition where the code performs reads or writes outside an allocated buffer; the supplied sources do not detail the specific Skia routine, allocation path or corruption primitive involved, so the exact trigger is not described in the available sources. The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H describes severity only: a network-reachable, low-complexity path requiring only that the victim load attacker-controlled content, with a scope change consistent with the reported ability to execute code outside the Chrome renderer sandbox on the host. The "before 156.0.8078.73" boundary defines exposure: patched builds are not affected, and no pre-disclosure exploitation signal accompanies the chrome-cve-admin report.

Lifecycle Timeline
3DescriptionCVE.org
Memory corruption in Skia in Google Chrome prior to 156.0.8078.73 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
Executive ViewAI
Google Chrome versions before 156.0.8078.73 contain a critical memory corruption flaw in the Skia graphics component that allows a remote attacker to execute arbitrary code outside the browser sandbox. This affects all unpatched Chrome users; a successful exploit could lead to full system compromise, data theft, and lateral movement within the network. Leadership should prioritize patching due to the severe impact and the availability of a vendor fix.
Apply vendor patch.
Threat Intelligence Overview
How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
