AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N
AC:H reflects mandatory renderer pre-compromise; C:L captures cross-origin data leak only; I:N and A:N confirmed by description; PR:N as attacker needs no privileges beyond the chained renderer access.

Uninitialized Use in Skia in Google Chrome prior to 151.0.7922.109 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Uninitialized memory use in Skia, Chrome's 2D graphics engine, exposes a cross-origin data leak primitive in Google Chrome prior to 151.0.7922.109. Exploitation is constrained to attackers who have already achieved renderer process compromise - making this a second-stage, chained vulnerability rather than a standalone initial-access vector. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has already achieved compromise of the Chrome renderer process through a separate vulnerability - this is an explicit precondition stated in the CVE description ('a remote attacker who had compromised the renderer process'). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The aggregate risk signals consistently point to a low real-world priority. … 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 | Update Google Chrome to version 151.0.7922.109 or later, which is confirmed as the vendor-released patch per the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_01193673229.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
