medium Tenable Cloud Security Plugin ID 467168

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: ipv4: Fix fib_nlmsg_size() for RTA_VIA
nexthops fib_nlmsg_size() still estimates nexthop space as if every gateway is encoded as an IPv4
RTA_GATEWAY attribute. IPv4 routes can also carry an IPv6 gateway, which fib_nexthop_info() dumps as
RTA_VIA. As a result, route notifications can allocate an skb that is too small. fib_dump_info() then
fails with -EMSGSIZE and rtmsg_fib() hits the WARN_ON() that marks such failures as a fib_nlmsg_size()
bug. With panic_on_warn set, this becomes a kernel panic. Mirror the actual nexthop dump layout in
fib_nlmsg_size(): account for IPv6 nexthop gateways dumped as RTA_VIA, for the no-header rtnexthop layout
used inside RTA_MULTIPATH, and for RTA_FLOW only when it is actually present. (CVE-2026-74657)

Solution

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