high Tenable Cloud Security Plugin ID 475751

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: nvme/ioctl: check SUBMIT_IO with
 nvme_cmd_allowed() Unlike IO_CMD / IO64_CMD, NVME_IOCTL_SUBMIT_IO never calls nvme_cmd_allowed().
 Unprivileged callers can thus issue I/O on a partition device or write through a read-only file
 descriptor. Pass flags and open_for_write through and reject disallowed commands with -EACCES.
 (CVE-2026-90227)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20198.0.0 or later.
