CVE-2026-79112 Overview
CVE-2026-79112 is an out-of-bounds read vulnerability in the Skia graphics library used by Google Chrome versions prior to 152.0.7977.65. Skia is Chrome's 2D graphics engine responsible for rendering paths, images, and text. A remote attacker who has already compromised the renderer process can exploit this flaw to read memory inside the sandbox by delivering a crafted HTML page. The issue is tracked under CWE-125: Out-of-bounds Read and classified as Low severity by the Chromium project.
Critical Impact
A compromised renderer process can read sensitive memory contents within the Chrome sandbox, potentially leaking data useful for further exploit chaining.
Affected Products
- Google Chrome for Desktop prior to 152.0.7977.65
- Chromium-based browsers embedding vulnerable Skia builds
- Applications using the affected Skia rendering component

Technical Details for CVE-2026-79112
Vulnerability Analysis
The vulnerability resides in Skia, the open-source 2D graphics library that Chrome uses to rasterize graphics primitives, paths, and images. An out-of-bounds read occurs when code reads memory beyond the intended buffer boundary. In this case, a crafted HTML page can trigger Skia code paths that access memory outside the allocated buffer during rendering operations.
Exploitation requires the attacker to have already compromised the renderer process, which typically implies chaining this issue with a prior renderer-side flaw. The out-of-bounds read then allows disclosure of memory inside the sandboxed renderer, which can include pointers, canvas data, or other sensitive process state. Attackers commonly use such reads to bypass Address Space Layout Randomization (ASLR) or stage sandbox escapes.
Root Cause
The root cause is missing or insufficient bounds validation within a Skia rendering routine. When processing attacker-controlled graphics input, the affected function reads past the end of a buffer. This is a classic [CWE-125] pattern where index or length values derived from untrusted input are not validated against the allocated buffer size before dereference.
Attack Vector
The attack vector is network-based and requires user interaction, such as visiting a malicious web page in the compromised renderer context. The attacker delivers HTML and associated graphics content that invokes the vulnerable Skia code path. Because the flaw only yields information disclosure within the sandbox, it is most valuable as one link in a multi-stage exploit chain rather than a standalone attack. Additional technical context is available in Chromium Issue Tracker #524864599.
Detection Methods for CVE-2026-79112
Indicators of Compromise
- Chrome renderer processes crashing with signals consistent with memory access violations while rendering graphics content
- Browser telemetry showing outbound connections to unfamiliar domains immediately before renderer crashes
- Pages loading unusual SVG, canvas, or WebGL payloads followed by anomalous child-process behavior
Detection Strategies
- Inventory installed Chrome versions across the fleet and flag any build below 152.0.7977.65
- Correlate browser crash reports with URL history to identify potentially malicious pages triggering Skia faults
- Monitor endpoint process trees for child processes spawned from chrome.exe renderer instances following crashes
Monitoring Recommendations
- Enable and centralize Chrome crash reporting to surface repeated Skia-related faults
- Ingest browser and endpoint telemetry into a centralized data lake for cross-source correlation
- Alert on renderer process anomalies such as unexpected memory reads or unusual IPC traffic to the browser process
How to Mitigate CVE-2026-79112
Immediate Actions Required
- Update Google Chrome to version 152.0.7977.65 or later on all managed endpoints
- Restart Chrome after the update completes to ensure the patched Skia binary is loaded
- Audit and update Chromium-based browsers and embedded frameworks that ship their own Skia builds
Patch Information
Google addressed the issue in the Chrome Stable Channel update to 152.0.7977.65. Refer to the Google Chrome Stable Update advisory and Chromium Issue Tracker #524864599 for release details. Enterprises using Chrome Browser Enterprise policies should push the updated version through their management channel.
Workarounds
- Enforce Chrome auto-update policies to ensure endpoints receive Stable Channel patches without user action
- Restrict browsing to trusted sites via enterprise web filtering until patching is verified across the fleet
- Apply site isolation and strict sandbox policies to limit the impact of any renderer-side compromise
