critical Tenable Cloud Security Plugin ID 467080

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: vxlan: re-fetch eth header after
 route_shortcircuit() Before route_shortcircuit(), the eth header pointer is cached from eth_hdr(skb).
 Inside route_shortcircuit(), pskb_may_pull() can be called, which may reallocate skb->head. In this case,
 returning to vxlan_xmit() leaves the cached eth pointer pointing to freed memory, leading to a use-after-
 free when dereferencing eth->h_dest. Fix this by updating eth = eth_hdr(skb) after calling
 route_shortcircuit(). (CVE-2026-80681)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.584.3 or later.
