## Executive Summary
It was discovered that curl, when built with GnuTLS support, had an out-of-bounds read in the WebSocket send path. An attacker could possibly use this issue to obtain sensitive information. (CVE-2026-107928) Maksim discovered that curl did not correctly include the interface binding in connection reuse decisions when CURLOPT_INTERFACE was used. An attacker could possibly use this issue to cause connections to go out from an unintended source address.

## Architectural & Systems Analysis
From an offensive security, vulnerability mitigation, and systems audit perspective:

- **Exploit Vector Analysis:** Evaluates unprivileged user namespaces, buffer boundaries, or cryptographic flaws.
- **Kernel Patch Hardening:** Kernel and compiler level guards (KASLR, CFI, stack canaries) mitigate weaponized exploitation.
- **Supply Chain Verification:** Highlights why signed SBOM (Software Bill of Materials) and reproducible builds are mandatory.

## Impact on the Open Ecosystem
Immediate patching and independent peer review across the open community safeguard critical internet infrastructure.
