high Tenable Cloud Security Plugin ID 470526

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: nvmet: fix refcount leak in
 nvmet_sq_create() In nvmet_sq_create(), a reference on the ctrl is taken via kref_get_unless_zero() before
 calling nvmet_check_sqid(). If nvmet_check_sqid() fails, the function returns the error directly without
 releasing the reference, leading to a leak. Fix this by jumping to the "ctrl_put" label, which already
 performs the necessary nvmet_ctrl_put(ctrl). This ensures the reference is properly released on this error
 path. (CVE-2026-72128)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.21 or later.
