high Tenable Cloud Security Plugin ID 470685

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: xsk: tighten UMEM headroom validation
 to account for tailroom and min frame The current headroom validation in xdp_umem_reg() could leave us
 with insufficient space dedicated to even receive minimum-sized ethernet frame. Furthermore if multi-
 buffer would come to play then skb_shared_info stored at the end of XSK frame would be corrupted. HW
 typically works with 128-aligned sizes so let us provide this value as bare minimum. Multi-buffer setting
 is known later in the configuration process so besides accounting for 128 bytes, let us also take care of
 tailroom space upfront. (CVE-2026-43093)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19804.0.0 or later.
