medium Tenable Self-Hosted Container Security Plugin ID 470086

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: net: ethtool: phy: avoid NULL deref
 when PHY driver is unbound phydev->drv can become NULL while the phy_device is still attached to its
 net_device, namely after the PHY driver is unbound via sysfs: echo <mdio_id> >
 /sys/bus/mdio_bus/drivers/<phy_drv>/unbind phy_remove() clears phydev->drv but doesn't call phy_detach(),
 so the phy_device stays in the link topology xarray and ethnl_req_get_phydev() still hands it back.
 ETHTOOL_MSG_PHY_GET then oopses on: rep_data->drvname = kstrdup(phydev->drv->name, GFP_KERNEL); drvname is
 already treated as optional by phy_reply_size(), phy_fill_reply() and phy_cleanup_data(), so just skip the
 allocation when there is no driver bound. (CVE-2026-64228)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19862.0.0 or later.
