high Tenable Cloud Security Plugin ID 475764

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: bpf: Disallow bpf_skb_pull_data() for
 LWT_SEG6LOCAL An LWT_SEG6LOCAL program can invalidate its cached SRH with bpf_lwt_seg6_adjust_srh() and
 then call bpf_skb_pull_data(). The latter may reallocate skb->head, leaving the per-CPU SRH pointer
 dangling. Post-program SRH validation then writes through that pointer. Disallow bpf_skb_pull_data() for
 LWT_SEG6LOCAL programs so the verifier rejects this unsafe helper combination. Other LWT program types
 continue to expose the helper through lwt_out_func_proto(). (CVE-2026-98383)

Solution

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