Uninitialized resource in Skia in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially read memory inside the sandbox via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Skia, the 2D graphics rendering library embedded in Google Chrome's renderer process, contains an uninitialized resource flaw that allows remote attackers to read stale sandbox memory contents by inducing a victim to visit a crafted HTML page. All Chrome versions prior to 152.0.7977.65 are affected across desktop platforms, with confidentiality impact confined to the renderer sandbox. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim to actively navigate to an attacker-controlled or compromised HTML page using a vulnerable Chrome version (prior to 152.0.7977.65) - the CVSS UI:R metric confirms that passive or drive-by exploitation without any user interaction is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N yields a base score of 6.5, reflecting unauthenticated network delivery with low complexity but mandatory victim interaction, high confidentiality impact, and no integrity or availability consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing content designed to trigger the uninitialized Skia resource path during rendering. When a victim navigates to this page with a vulnerable Chrome version, stale memory contents from the renderer process are read and may be observable by the attacker, potentially disclosing sensitive in-process data such as previously rendered page content or credentials. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later; this is the vendor-released patch per the Chrome stable channel update advisory at chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
