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。

  - RDMA/srp不从 srp_abort() 调用 scsi_done() 在 scmd_eh_abort_handler() 调用 SCSI LLD eh_abort_handler 回调之后它将执行下列操作之一* 调用 scsi_queue_insert()。 * 调用 scsi_finish_command()。 * 调用 scsi_eh_scmd_add()。因此SCSI 中止处理程序不得调用 scsi_done()。
    否则上述所有操作都将触发释放后使用。因此从 srp_abort() 中删除 scsi_done() 调用。在返回 SUCCESS 之前保留 srp_free_req() 调用因为如果返回 SUCCESS我们可能不会再看到该命令。 (CVE-2023-52515)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

AlmaLinux 9.2 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.2：CLSA-2026：1787935638公告中提及的多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：fs/mount_setattr: always cleanup mount_kattr Make sure that finish_mount_kattr() is called after mount_kattr was succesfully built in both the success and failure case to prevent leaking any references we took when we built it. We returned early if path lookup failed thereby risking to leak an additional reference we took when building mount_kattr when an idmapped mount was requested. (CVE-2021-46923)

  - 已修复 Linux 内核中的下列漏洞：vdpa: ifcvf: Do proper cleanup if IFCVF init fails ifcvf_mgmt_dev leaks memory if it is not freed before returning. Call is made to correct return statement so memory does not leak. ifcvf_init_hw does not take care of this so it is needed to do it here. (CVE-2022-48706)

  - 已修复 Linux 内核中的下列漏洞：tracing/histogram: Fix a potential memory leak for kstrdup() kfree() is missing on an error path to free the memory allocated by kstrdup(): p = param = kstrdup(data->params[i], GFP_KERNEL); So it is better to free it via kfree(p). (CVE-2022-48768)

  - 已修复 Linux 内核中的下列漏洞：efi: fix NULL-deref in init error path In cases where runtime services are not supported or have been disabled, the runtime services workqueue will never have been allocated. Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer. (CVE-2022-48879)

  - 已修复 Linux 内核中的下列漏洞：RDMA/srp: Do not call scsi_done() from srp_abort() After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler callback, it performs one of the following actions: * Call scsi_queue_insert(). * Call scsi_finish_command(). * Call scsi_eh_scmd_add(). Hence, SCSI abort handlers must not call scsi_done(). Otherwise all the above actions would trigger a use-after-free. Hence remove the scsi_done() call from srp_abort(). Keep the srp_free_req() call before returning SUCCESS because we may not see the command again if SUCCESS is returned. (CVE-2023-52515)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。
