high Tenable Cloud Security Plugin ID 467680

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: btrfs: fix double free in
 create_space_info() error path When kobject_init_and_add() fails, the call chain is: create_space_info()
 -> btrfs_sysfs_add_space_info_type() -> kobject_init_and_add() -> failure ->
 kobject_put(&space_info->kobj) -> space_info_release() -> kfree(space_info) Then control returns to
 create_space_info(): btrfs_sysfs_add_space_info_type() returns error -> goto out_free -> kfree(space_info)
 This causes a double free. Keep the direct kfree(space_info) for the earlier failure path, but after
 btrfs_sysfs_add_space_info_type() has called kobject_put(), let the kobject release callback handle the
 cleanup. (CVE-2026-46129)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.395.73 or later.
