aiohttp: AIOHTTP: Denial of Service via malformed HTTP responses

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework. This vulnerability involves an out-of-bounds heap read in the C response parser when processing malformed HTTP responses. An attacker operating a malicious server, or even an accidental malformed response, could exploit th...

CVE-2026-68340

The CVE-2026-68340 entry concerns the Linux kernel hwmon OCC poll response parser. The root cause is using a static backing-array capacity as the boundary for sensor data blocks, rather than the actual data_length, which can allow a truncated transport response to cause the parser to read beyond ...

DEBIAN-CVE-2026-69244

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 trigg...

CVE-2026-8696

CVE-2026-8696 affects radare2 6.1.5, specifically the GDB client core's gdbr_pids_list() function. The vulnerability is a use-after-free that can be triggered by malformed thread information responses, where qsThreadInfo fails after qfThreadInfo allocates RDebugPid structures. This leads to a dou...
