"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-005497 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    ata: libata-core: Fix null pointer dereference on error

    If the ata_port_alloc() call in ata_host_alloc() fails,
    ata_host_release() will get called.

    However, the code in ata_host_release() tries to free ata_port struct
    members unconditionally, which can lead to the following:
