NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-aiohttp package and not the python3-aiohttp package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, it is possible to bypass the max_line_size check in parts of an HTTP request in the C parser. If using the optimised C parser (the default in pre-built wheels), then an attacker may be able to send oversized lines through the HTTP parser and use an excessive amount of memory, potentially leading to DoS. This vulnerability is fixed in 3.14.1.
