critical Tenable Cloud Security Plugin ID 466275

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: ipvlan: inherit needed_headroom and
 needed_tailroom from phy_dev ipvlan devices inherit hard_header_len from phy_dev during ipvlan_init(), but
 leave needed_headroom and needed_tailroom set to 0. When the underlying phy_dev (or stacked lower device)
 requires extra headroom or tailroom for headers/trailers (e.g. macsec, ipsec, wireguard, tunnels, or veth
 with rx headroom), upper layers calculating packet headroom and tailroom fail to reserve sufficient space.
 This can result in reallocation overhead, skb headroom underflows, or KASAN slab-use-after-free crashes
 when dev_hard_header() / ipvlan_hard_header() prepends header data or when lower devices append tailroom.
 Fix this by: 1. Inheriting needed_headroom and needed_tailroom from phy_dev in ipvlan_init(). 2.
 Propagating needed_headroom and needed_tailroom updates to attached ipvlans in ipvlan_device_event() when
 receiving NETDEV_FEAT_CHANGE events. (CVE-2026-74744)

Solution

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