CVE-2026-56855

Опубликовано: 03 сент. 2026
Источник: ubuntu
Приоритет: medium
EPSS Низкий
CVSS3: 7.5

Описание

Previously, after a channel has been established, a malicious peer could send crafted messages that would deadlock the entire connection. Now, we handle all RFC 4254 channel messages; global requests are handled explicitly. Then, treat all other messages as a protocol error and tear the connection down instead of buffering and blocking.
