Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：block: ublk: extending queue_size to fix overflow When validating drafted SPDK ublk target, in a case that assigning large queue depth to multiqueue ublk device, ublk target would run into a weird incorrect state. During rounds of review and debug, An overflow bug was found in ublk driver. In ublk_cmd.h, UBLK_MAX_QUEUE_DEPTH is 4096 which means each ublk queue depth can be set as large as 4096. But when setting qd for a ublk device, sizeof(struct ublk_queue) + depth * sizeof(struct ublk_io) will be larger than 65535 if qd is larger than 2728. Then queue_size is overflowed, and ublk_get_queue() references a wrong pointer position. The wrong content of ublk_queue elements will lead to out-of-bounds memory access. Extend queue_size in ublk_device as unsigned int. (CVE-2023-52980)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011323 advisory.

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

    block: ublk: extending queue_size to fix overflow

    When validating drafted SPDK ublk target, in a case that     assigning large queue depth to multiqueue ublk device,     ublk target would run into a weird incorrect state. During     rounds of review and debug, An overflow bug was found     in ublk driver.

    In ublk_cmd.h, UBLK_MAX_QUEUE_DEPTH is 4096 which means     each ublk queue depth can be set as large as 4096. But     when setting qd for a ublk device,     sizeof(struct ublk_queue) + depth * sizeof(struct ublk_io)     will be larger than 65535 if qd is larger than 2728.
    Then queue_size is overflowed, and ublk_get_queue()     references a wrong pointer position. The wrong content of     ublk_queue elements will lead to out-of-bounds memory     access.

    Extend queue_size in ublk_device as unsigned int.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue 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.
