๐ก๏ธ **Root Cause**: **Out-of-Bounds Read** in the V8 JavaScript engine. <br>๐ **Flaw**: Improper boundary checks allow accessing memory locations that should be restricted.โฆ
๐ฆ **Affected**: **Google Chrome** (Desktop). <br>๐ซ **Version**: All versions **prior to 116.0.5845.110**. <br>โ๏ธ **Component**: The **V8** JavaScript engine module is the specific target.
๐ **Threshold**: **LOW**. <br>๐ **Auth**: No authentication required. <br>๐ฑ๏ธ **Config**: Triggered simply by **visiting a malicious webpage**. No user interaction beyond loading the page is needed.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp?**: **YES**. <br>๐ **PoC**: Available on GitHub (e.g., `tianstcht/CVE-2023-4427`). <br>โ ๏ธ **Note**: Exploitation involves complex techniques like **ASLR bypass** using iframes, but proof-of-concept exists.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: <br>1. Check Chrome Version: Go to `chrome://settings/help`. <br>2. Verify: Is version **< 116.0.5845.110**? <br>3. Scan: Use vulnerability scanners detecting V8 out-of-bounds reads in Chrome.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed?**: **YES**. <br>๐ฉน **Patch**: Update Chrome to version **116.0.5845.110** or later. <br>๐ข **Source**: Official Chrome Stable Release notes confirm the fix.
