Severity by source
AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N
Local program plus social engineering gives AV:L/UI:R/PR:N; the OOB read leaks memory across the sandbox (S:C, C:H) with no write or crash (I:N/A:N).

Out of bounds read in DataTransfer in Google Chrome prior to 153.0.8010.52 allowed a local attacker leveraging social engineering to read memory outside the sandbox via a local program. (Chromium security severity: Medium)
AnalysisAI
Memory disclosure in Google Chrome prior to 153.0.8010.52 allows a local attacker to read out-of-bounds data through the browser's DataTransfer implementation, with the sandbox-crossing scope change (S:C) in the CVSS vector indicating the leaked memory can originate outside the renderer process rather than from within the attacker's own context. Per the assessed vector (AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N, base 6.3) exploitation requires the attacker to already be running a local program on the victim's machine and to use social engineering to obtain user interaction, and it produces only confidentiality impact with no integrity or availability effect, so this is an information-disclosure bug rather than a sandbox escape or code-execution primitive. …

Vulnerability AssessmentAI
| Exploitation | Requires local access: the attacker must run a local program on the victim's machine AND use social engineering to obtain user interaction (UI:R), targeting Chrome versions prior to 153.0.8010.52 on desktop. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but low-priority issue. … 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: upgrade to Google Chrome 153.0.8010.52 or later, which is the version Google shipped to fix this issue; use the built-in updater via chrome://settings/help or deploy the corresponding enterprise MSI (Windows), PKG (macOS) or DEB/RPM (Linux) package and verify the reported version, then restart the browser so running processes pick up the new binary, and do the same for any Chromium-based browser once its vendor rebases. … Detailed patch versions, workarounds, and compensating controls in full report. |
