high Tenable Self-Hosted Container Security Plugin ID 465858

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: vhost: Take a reference on the task in
struct vhost_task. vhost_task_create() creates a task and keeps a reference to its task_struct. That task
may exit early via a signal and its task_struct will be released. A pending vhost_task_wake() will then
attempt to wake the task and access a task_struct which is no longer there. Acquire a reference on the
task_struct while creating the thread and release the reference while the struct vhost_task itself is
removed. If the task exits early due to a signal, then the vhost_task_wake() will still access a valid
task_struct. The wake is safe and will be skipped in this case. (CVE-2025-40024)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.439.2 or later.
