UBUNTU-CVE-2026-47329: Low severity ubuntu/linux-hwe-edge vulnerability

Q: Who can exploit this issue?

An unprivileged local user can trigger the flaw. It is therefore relevant to systems where untrusted users, tenants, or workloads can obtain local user access.

Q: What access or interaction is required for exploitation?

Exploitation requires local access and low privileges. No user interaction is required.

Q: Which Ubuntu kernel packages are identified as affected?

The affected software list includes ubuntu/linux, ubuntu/linux-riscv, ubuntu/linux-realtime, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-azure-fde, ubuntu/linux-aws, and ubuntu/linux-oracle.

Q: What is the potential impact?

The issue could cause AppArmor notification responses with crafted name-field sizes to be handled incorrectly. The provided severity vector indicates an integrity impact, with no stated confidentiality or availability impact.

Published May 28, 2026

Updated

Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches which fail to validate invalid sizes of the name field in AppAmor notification responses. The bug can be triggered by an unprivileged local user and could result in handling of crafted responses.
