high Tenable Self-Hosted Container Security Plugin ID 466074

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
 ip4ip6_err() Oskar Kjos reported the following problem. ip4ip6_err() calls icmp_send() on a cloned skb
 whose cb[] was written by the IPv6 receive path as struct inet6_skb_parm. icmp_send() passes IPCB(skb2) to
 __ip_options_echo(), which interprets that cb[] region as struct inet_skb_parm (IPv4). The layouts differ:
 inet6_skb_parm.nhoff at offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rr value.
 __ip_options_echo() then reads optlen from attacker-controlled packet data at sptr[rr+1] and copies that
 many bytes into dopt->__data, a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE). To fix this we
 clear skb2->cb[], as suggested by Oskar Kjos. Also add minimal IPv4 header validation (version == 4, ihl
 >= 5). (CVE-2026-43037)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.5 or later.
