Last updated on: 2026-06-09

Assigner: Canonical Ltd.

Description
Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which incorrectly validate the size of an internal structure, leading to an out-of-bounds read in notification handling code. The bug can be triggered by an unprivileged local user and can result in information disclosure from adjacent slab objects.

Executive Summary

This vulnerability exists in Ubuntu Linux versions 6.8, 6.17, and 7.0 within the AppArmor SAUCE patches. It involves incorrect validation of the size of an internal structure, which leads to an out-of-bounds read in the notification handling code.

An unprivileged local user can trigger this bug, causing the system to read memory beyond the intended boundaries, potentially disclosing information from adjacent slab objects.

Impact Analysis

The vulnerability can lead to information disclosure, meaning that sensitive data stored in adjacent memory areas (slab objects) could be exposed to an unprivileged local user.

Since the vulnerability allows reading memory out-of-bounds, it could compromise confidentiality but does not affect integrity or availability.
