high Tenable Cloud Security Plugin ID 466257

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: tcp: ipv6: clamp default adverting MSS
 to avoid GSO_BY_FRAGS (0xFFFF) When MTU is large, ip6_default_advmss() can return IPV6_MAXPLEN (65535).
 This is interpreted by TCP as mss_clamp, allowing the MSS to reach 65535. However, 0xFFFF is also used as
 a magic value GSO_BY_FRAGS in the kernel. If a TCP packet with gso_size=0xFFFF is passed to skb_segment(),
 it will be mistakenly treated as GSO_BY_FRAGS, leading to a NULL pointer dereference because local TCP
 packets do not use frag_list. Fix this by returning min(IPV6_MAXPLEN, GSO_BY_FRAGS - 1) (65534) from
 ip6_default_advmss() when MTU is large. Also update the stale comment in ip6_default_advmss() which
 suggested that IPV6_MAXPLEN is returned to mean "any MSS". (CVE-2026-72502)

Solution

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