Official Description
Ubuntu Linux 6.8, 7.17 and 7.0 contain AppArmor SAUCE patches which can, under certain circumstances, use an uninitialized variable in notification handling code. The bug can be triggered by an unprivileged local user and can result in the incorrect caching of AppArmor notification responses.
Technical Analysis
CVE-2026-47330 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
