CVE-2025-53853 — AI Deep Analysis Summary

🚨 **Essence**: A critical heap buffer overflow in `libbiosig`'s ISHNE parsing function. 💥 **Consequences**: Attackers can trigger **Arbitrary Code Execution (ACE)**.…

🛡️ **Root Cause**: **CWE-122** (Heap-based Buffer Overflow). The flaw lies in how the library handles input during the ISHNE format parsing, failing to validate buffer boundaries properly.

🏢 **Affected**: **The Biosig Project**'s open-source library **libbiosig**. 📦 **Version**: Specifically **v3.9.0**. Any application integrating this version for biomedical signal processing is at risk.

👑 **Privileges**: **Full System Control**. Due to ACE, hackers can execute code with the privileges of the vulnerable process.…

⚡ **Threshold**: **LOW**. 🌐 **Network**: Attack Vector is Network (AV:N). 🔓 **Auth**: No Privileges Required (PR:N). 🖱️ **User Interaction**: None Required (UI:N). Easy to exploit remotely.

🔍 **Public Exploit**: **No**. The `pocs` field is empty.…

🔎 **Self-Check**: Scan your environment for **libbiosig v3.9.0**. Look for applications processing **ISHNE** biomedical signal formats.…

🛠️ **Fix**: The data does not explicitly list a patch version. However, as an open-source library, the vendor (**The Biosig Project**) is the source for updates.…

🚧 **Workaround**: If no patch is available: 1. **Disable** ISHNE parsing functionality if not strictly needed. 2. **Isolate** services processing these files. 3.…

🔥 **Urgency**: **CRITICAL**. With a CVSS score of **9.8** (High), Network-accessible, and no user interaction required, this is a top-priority vulnerability.…
