Severity by source
AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N
AC:H captures the mandatory pre-compromised renderer prerequisite; S:C reflects cross-sandbox memory read; C:L for limited stale-memory disclosure; no integrity or availability impact applies.

Uninitialized resource in GPU in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to read memory outside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Memory read outside the renderer sandbox in Google Chrome's GPU component affects all desktop versions prior to 153.0.8010.36. An uninitialized GPU resource (CWE-908) enables an attacker who has already gained code execution inside the renderer process to read stale memory contents from outside the sandbox boundary via a crafted HTML page, exposing browser process memory or heap addresses. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two explicit prerequisites: (1) the attacker must have already achieved code execution within Chrome's renderer process via a separate vulnerability - this is the critical limiting condition stated verbatim in the description ('had compromised the renderer process') and is reflected in AC:H; and (2) the victim user must visit a crafted HTML page that triggers the vulnerable GPU operations (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.4 (Low) with vector AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N accurately reflects the isolated risk: exploitation is gated on a pre-compromised renderer (AC:H), requires user interaction (UI:R), and delivers only limited confidentiality impact (C:L) with no integrity or availability consequence. … 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 | Vendor-released patch: Chrome 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
