BREW-advai-cli-CVE-2026-69244 — AIOHTTP: Out-of-bounds heap read in C HTTP response parser error path (malformed chunked response)

Affected: Homebrew: advai-cli

### Summary

An out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response.

### Impact

An attacker controlled server, or possibly an accidental response could trigger a DoS in the client.

### Workaround

If unable to upgrade, the Python parser is unaffected and can be used with `AIOHTTP_NO_EXTENSIONS=1`.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.3, an out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. An attacker controlled server, or possibly an accidental response, could trigger a DoS in the client. The vulnerable path was error message construction in aiohttp/_http_parser.pyx, where an llhttp error-position pointer was used to build a snippet for malformed chunked responses and malformed request or response bytes at the buffer end. This issue is fixed in version 3.14.3.
