The blk_queue_enter() from blkg_conf_prep() is used to protect against policy deactivation, which is already protected with blkcg_mutex, hence convert blk_queue_enter() to blkcg_mutex to fix this problem. Meanwhile, consider that blkcg_mutex is held after queue is freezed from policy deactivation, also convert blkg_alloc() to use GFP_NOIO.

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 remote Ubuntu 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8030-1 advisory.

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    CPU0 CPU1 ---- ---- lock(&q->q_usage_counter(queue)#3); lock(&q->rq_qos_mutex);
    lock(&q->q_usage_counter(queue)#3); lock(&q->sysfs_lock); Root cause is that queue_usage_counter is     grabbed with rq_qos_mutex held in blkg_conf_prep(), while queue should be freezed before rq_qos_mutex from     other context. The blk_queue_enter() from blkg_conf_prep() is used to protect against policy deactivation,     which is already protected with blkcg_mutex, hence convert blk_queue_enter() to blkcg_mutex to fix this     problem. Meanwhile, consider that blkcg_mutex is held after queue is freezed from policy deactivation,     also convert blkg_alloc() to use GFP_NOIO. (CVE-2025-68178)
