Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.104.149

high Tenable Cloud Security Plugin ID 471990

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: hv_netvsc: reject RSS hash key
 programming without RX indirection table RSS configuration requires a valid RX indirection table. When the
 device reports a single receive queue, rndis_filter_device_add() does not allocate an indirection table,
 accepting RSS hash key updates in this state leads to a hang. Fix this by gating netvsc_set_rxfh() on
 ndc->rx_table_sz and return -EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device
 capabilities and prevents incorrect behavior. (CVE-2026-23054)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.104.149 or later.
