CVE-2026-22891 — AI Deep Analysis Summary

🚨 **Essence**: A critical heap buffer overflow in **libbiosig** (BioSig Project). 📉 **Consequences**: Attackers can trigger **Arbitrary Code Execution** (ACE).…

🔍 **Root Cause**: **CWE-122** (Heap-based Buffer Overflow). 🧠 **Flaw**: The vulnerability lies specifically in the **Intan CLP parsing function**. Improper bounds checking allows writing beyond allocated memory limits. 💥

👥 **Affected**: **The Biosig Project** vendors. 📦 **Product**: **libbiosig**. 📅 **Version**: Specifically **v3.9.2** is cited. ⚠️ Other versions may be vulnerable, but 3.9.2 is the confirmed entry point in this report. 🏥

💻 **Hackers' Power**: Full **Arbitrary Code Execution**. 🔓 **Privileges**: Can run code with the **application's privileges**. 📂 **Data**: Complete **Confidentiality, Integrity, and Availability** loss (CVSS H/H/H).…

📉 **Threshold**: **LOW**. 🚫 **Auth**: No authentication required (**PR:N**). 🖱️ **UI**: No user interaction needed (**UI:N**). 🌐 **Network**: Remote exploitability (**AV:N**). 🎯 **Complexity**: Low (**AC:L**).…

🚫 **Public Exploit**: **No**. 📄 **PoCs**: The `pocs` array is empty in the data. 🔒 **Status**: While no public PoC is listed, the low CVSS complexity suggests it could be weaponized quickly. 🕵️‍♀️

🔎 **Self-Check**: Scan for **libbiosig v3.9.2**. 🔍 **Feature**: Look for usage of **Intan CLP file parsing**. 🛠️ **Tools**: Use SAST/DAST tools to detect heap overflow patterns in C/C++ bio-signal processing modules. 📋

🛡️ **Official Fix**: **Unknown/Not Listed**. 📜 **References**: A Talos Intelligence report is linked, but no specific patch version or download link is provided in the data. 🔄 Check vendor updates immediately. 📢

🚧 **Workaround**: **Disable Intan CLP parsing**. 🚫 **Mitigation**: If possible, restrict input sources or use a **whitelist** for supported file formats. 🛑 Avoid processing untrusted CLP files entirely. 🧱

🔥 **Urgency**: **CRITICAL**. 🚨 **Priority**: **P1**. With **CVSS 9.8** (implied by H/H/H) and **Remote/No-Auth** access, this is a high-priority patching target. 🏃‍♂️ Update or mitigate immediately! ⏳
