An update of the linux package has been released.

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

  - null_blk: free zones array on device power-off null_init_zoned_dev() allocates dev->zones when a zoned     device is powered on, but null_del_dev() never frees it on power-off; dev->zones is only freed later in     null_free_dev(), when the configfs directory is removed. If the device is powered off and then on again,     null_init_zoned_dev() allocates a new array and overwrites the dev->zones pointer, leaking the previous     allocation each power cycle. Free dev->zones in null_del_dev() via null_free_zoned_dev() to solve it. And     calling null_free_zoned_dev() in null_free_dev() is no longer necessary because every caller already     invokes null_del_dev() first: via nullb_group_drop_item() before nullb_device_release(), in the     null_add_dev() error path of null_create_dev(), and in null_destroy_dev(). Remove the redundant call. And     take &lock around zone_cond_store() in the two store wrappers to serialize dev->zones check-and-deref     against its alloc/free, which already run under &lock. The reason there was no problem before is that only     nullb_device_release() or null_exit() frees the dev->zones, which guarantees that subsequent users won't     access the configfs interface. (CVE-2026-90187)

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