critical Tenable Cloud Security Plugin ID 466276

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: tunnels: load network headers after
 skb_cow() in iptunnel_pmtud_build_icmp[v6]() Sashiko found that iptunnel_pmtud_build_icmp() and
 iptunnel_pmtud_build_icmpv6() were caching ip_hdr() and ipv6_hdr() before an skb_cow() call which can
 reallocate skb->head. Fix this possible UAF by initializing the local variables after the skb_cow() call.
 Remove skb_reset_network_header() calls which were not needed. (CVE-2026-63994)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.2 or later.
