Out of bounds read in CrashReporting in Google Chrome prior to 152.0.7977.82 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
Out-of-bounds memory read in Google Chrome's CrashReporting component (all versions prior to 152.0.7977.82) allows an attacker who has already compromised the renderer process to read memory beyond sandbox boundaries via a crafted HTML page, leaking limited cross-process memory contents. The exploitation chain is constrained by a hard prerequisite - renderer compromise must precede this step - placing the flaw in a post-exploitation context rather than as a standalone initial access vector. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two stacked conditions: first, the attacker must already have code execution within Chrome's renderer process (typically achieved via a separate, independent renderer RCE vulnerability); second, the target user must be interacting with a crafted HTML page that triggers the renderer compromise and subsequent crash-report manipulation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.1 (Low) accurately reflects the constrained real-world impact: AC:H captures the hard prerequisite of renderer compromise, C:L reflects only partial memory disclosure, and the absence of integrity or availability impact keeps the score low. … 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 152.0.7977.82 or later, available via Chrome's built-in update mechanism (Settings → Help → About Google Chrome) or the official stable channel release at chromereleases.googleblog.com. … Detailed patch versions, workarounds, and compensating controls in full report. |
