critical Tenable Cloud Security Plugin ID 466294

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: ip6_tunnel: clear skb2->cb[] in
ip6ip6_err() ip6ip6_err() clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet,
and then passes the clone to icmpv6_send(). The clone still carries the outer packet's inet6_skb_parm in
skb->cb. If the outer packet had a Home Address Option, IP6CB(skb2)->dsthao remains non-zero after
skb_pull(). icmpv6_send() later calls mip6_addr_swap(), which uses that stale dsthao offset against the
quoted inner packet. A malformed inner destination-options header can then make the HAO lookup and address
swap run past the end of the quoted packet and corrupt skb_shared_info. Clear skb2->cb[] before pulling
the quoted inner IPv6 packet so the reply path does not reuse metadata left by the outer IPv6 stack.
(CVE-2026-74597)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
