In the Linux kernel, the following vulnerability has been resolved: apparmor: fix unprivileged local user can do privileged policy management An unprivileged local user can load, replace, and remove profiles by opening the apparmorfs interfaces, via a confused deputy attack, by passing the opened fd to a privileged process, and getting the privileged process to write to the interface. This does require a privileged target that can be manipulated to do the write for the unprivileged process, but once such access is achieved full policy management is possible and all the possible implications that implies: removing confinement, DoS of system or target applications by denying all execution, by-passing the unprivileged user namespace restriction, to exploiting kernel bugs for a local privilege escalation. The policy management interface can not have its permissions simply changed from 0666 to 0600 because non-root processes need to be able to load policy to different policy namespaces. Instead ensure the task writing the interface has privileges that are a subset of the task that opened the interface. This is already done via policy for confined processes, but unconfined can delegate access to the opened fd, by-passing the usual policy check.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8141-1 advisory.

    Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM).
    An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor     profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege     escalation, or possibly escape a container. (LP: #2143853, CVE-2026-23268, CVE-2026-23269)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - apparmor: fix unprivileged local user can do privileged policy management An unprivileged local user can     load, replace, and remove profiles by opening the apparmorfs interfaces, via a confused deputy attack, by     passing the opened fd to a privileged process, and getting the privileged process to write to the     interface. This does require a privileged target that can be manipulated to do the write for the     unprivileged process, but once such access is achieved full policy management is possible and all the     possible implications that implies: removing confinement, DoS of system or target applications by denying     all execution, by-passing the unprivileged user namespace restriction, to exploiting kernel bugs for a     local privilege escalation. The policy management interface can not have its permissions simply changed     from 0666 to 0600 because non-root processes need to be able to load policy to different policy     namespaces. Instead ensure the task writing the interface has privileges that are a subset of the task     that opened the interface. This is already done via policy for confined processes, but unconfined can     delegate access to the opened fd, by-passing the usual policy check. (CVE-2026-23268)

Note that Nessus relies on the presence of the package as reported by the vendor.
