high Tenable Cloud Security Plugin ID 467675

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: netfilter: nft_inner: Fix IPv6
 inner_thoff desync In nft_inner_parse_l2l3(), when processing inner IPv6 packets, ipv6_find_hdr()
 correctly computes the transport header offset traversing all extension headers, but the result is
 immediately overwritten with nhoff + sizeof(_ip6h) (40 bytes), which only accounts for the IPv6 base
 header. This creates a desync between inner_thoff (wrong — points to extension header start) and l4proto
 (correct — e.g., IPPROTO_TCP), enabling transport header forgery and potential firewall bypass. This issue
 affects stable versions from Linux 6.2. For comparison, the normal (non-inner) IPv6 path correctly
 preserves ipv6_find_hdr()'s result. Removing the incorrect overwrite ensures that ipv6_find_hdr()'s
 calculated transport header offset is preserved, thereby fixing the desynchronization. (CVE-2026-46244)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.381.177 or later.
