Lifecycle Timeline
4DescriptionCVE.org
Out of bounds read in Skia in Google Chrome prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process to read memory inside the sandbox via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Out-of-bounds read in Chrome's Skia graphics library exposes sandbox memory to attackers who have already compromised the renderer process. Exploitation requires a prior renderer compromise plus user interaction with a crafted HTML page, making this a chained second-stage information disclosure rather than a standalone critical flaw. …

Vulnerability AssessmentAI
| Exploitation | Exploitation has two hard prerequisites: (1) the attacker must have already achieved code execution within the Chrome renderer process via a separate, independent vulnerability - this CVE is not independently exploitable from a clean browser state; (2) the victim must interact with a crafted HTML page (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk here is meaningfully lower than the raw CVSS 6.5 suggests. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later, as documented in the Chrome stable channel release advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
