An update of the linux package has been released.

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8201-1 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.

Tenable has extracted the preceding description block directly from the Ubuntu 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.

  - In the Linux kernel, the following vulnerability has been resolved: apparmor: fix race on rawdata     dereference There is a race condition that leads to a use-after-free situation: because the rawdata inodes     are not refcounted, an attacker can start open()ing one of the rawdata files, and at the same time remove     the last reference to this rawdata (by removing the corresponding profile, for example), which frees its     struct aa_loaddata; as a result, when seq_rawdata_open() is reached, i_private is a dangling pointer and     freed memory is accessed. The rawdata inodes weren't refcounted to avoid a circular refcount and were     supposed to be held by the profile rawdata reference. However during profile removal there is a window     where the vfs and profile destruction race, resulting in the use after free. Fix this by moving to a     double refcount scheme. Where the profile refcount on rawdata is used to break the circular dependency.
    Allowing for freeing of the rawdata once all inode references to the rawdata are put. (CVE-2026-23410)

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