Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - blk-mqキューを再初期化する際に quiesced のエレベータースイッチを使用します。ハードウェアキューを再初期化する際に、hctx の run_work がエレベータースイッチと競合する可能性があります。このコンテキストではキューはフリーズするだけですが、リクエストの割り当てが妨げられるだけで、hctx の動作は実行されます。作業により、エレベーターポインターが破壊される可能性があります。これにより、use-after-free エラーとカーネルパニックが発生する可能性があります以下の例。代わりに quiesced エレベータースイッチを使用し、以前のものはローカルでのみ使用されるため、静的にします。 nvme nvme0コントローラー nvme nvme032/0/0 default/read/poll キューのリセット BUG

An update of the linux package has been released.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-010845 advisory.

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

    blk-mq: use quiesced elevator switch when reinitializing queues

    The hctx's run_work may be racing with the elevator switch when     reinitializing hardware queues. The queue is merely frozen in this     context, but that only prevents requests from allocating and doesn't     stop the hctx work from running. The work may get an elevator pointer     that's being torn down, and can result in use-after-free errors and     kernel panics (example below). Use the quiesced elevator switch instead,     and make the previous one static since it is now only used locally.

Tenable has extracted the preceding description block directly from the EulerOS Virtualization 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - blk-mq: use quiesced elevator switch when reinitializing queues The hctx's run_work may be racing with the     elevator switch when reinitializing hardware queues. The queue is merely frozen in this context, but that     only prevents requests from allocating and doesn't stop the hctx work from running. The work may get an     elevator pointer that's being torn down, and can result in use-after-free errors and kernel panics     (example below). Use the quiesced elevator switch instead, and make the previous one static since it is     now only used locally. nvme nvme0: resetting controller nvme nvme0: 32/0/0 default/read/poll queues BUG:
