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: ublk: fix use-after-free in     ublk_partition_scan_work A race condition exists between the async partition scan work and device teardown     that can lead to a use-after-free of ub->ub_disk: 1. ublk_ctrl_start_dev() schedules partition_scan_work     after add_disk() 2. ublk_stop_dev() calls ublk_stop_dev_unlocked() which does: - del_gendisk(ub->ub_disk)
    - ublk_detach_disk() sets ub->ub_disk = NULL - put_disk() which may free the disk 3. The worker     ublk_partition_scan_work() then dereferences ub->ub_disk leading to UAF Fix this by using     ublk_get_disk()/ublk_put_disk() in the worker to hold a reference to the disk during the partition scan.
    The spinlock in ublk_get_disk() synchronizes with ublk_detach_disk() ensuring the worker either gets a     valid reference or sees NULL and exits early. Also change flush_work() to cancel_work_sync() to avoid     running the partition scan work unnecessarily when the disk is already detached. (CVE-2026-22995)

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