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

  - block: fix rq-qos breakage from skipping rq_qos_done_bio() a647a524a467 (block: don't call     rq_qos_ops->done_bio if the bio isn't tracked) made bio_endio() skip rq_qos_done_bio() if BIO_TRACKED is     not set. While this fixed a potential oops, it also broke blk-iocost by skipping the done_bio callback for     merged bios. Before, whether a bio goes through rq_qos_throttle() or rq_qos_merge(), rq_qos_done_bio()     would be called on the bio on completion with BIO_TRACKED distinguishing the former from the latter.
    rq_qos_done_bio() is not called for bios which wenth through rq_qos_merge(). This royally confuses blk-     iocost as the merged bios never finish and are considered perpetually in-flight. One reliably reproducible     failure mode is an intermediate cgroup geting stuck active preventing its children from being activated     due to the leaf-only rule, leading to loss of control. The following is from resctl-bench protection     scenario which emulates isolating a web server like workload from a memory bomb run on an iocost     configuration which should yield a reasonable level of protection. # cat /sys/block/nvme2n1/device/model     Samsung SSD 970 PRO 512GB # cat /sys/fs/cgroup/io.cost.model 259:0 ctrl=user model=linear rbps=834913556     rseqiops=93622 rrandiops=102913 wbps=618985353 wseqiops=72325 wrandiops=71025 # cat     /sys/fs/cgroup/io.cost.qos 259:0 enable=1 ctrl=user rpct=95.00 rlat=18776 wpct=95.00 wlat=8897 min=60.00     max=100.00 # resctl-bench -m 29.6G -r out.json run protection::scenario=mem-hog,loops=1 ...

Fix it by introducing a new flag BIO_QOS_MERGED to mark merged bios and calling     rq_qos_done_bio() on them too. For consistency and clarity, rename BIO_TRACKED to BIO_QOS_THROTTLED. The     flag checks are moved into rq_qos_done_bio() so that it's next to the code paths that set the flags. With     the patch applied, the above same benchmark shows: # resctl-bench -m 29.6G -r out.json run     protection::scenario=mem-hog,loops=1 ...

Tenable has extracted the preceding description block directly from the EulerOS kernel 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 version of kernel installed on the remote host is prior to 5.15.54-25.126. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-005 advisory.
