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: bonding: do not clear
curr_active_slave prematurely when releasing all slaves When releasing all slaves during bond destruction
(all == true), __bond_release_one() unconditionally clears bond->curr_active_slave to NULL in every
iteration. If a backup slave is released before the active slave, bond_alb_deinit_slave() triggers
rlb_teach_disabled_mac_on_primary(), which increments the active slave dev promiscuity counter and sets
bond_info->primary_is_promisc = 1. Because bond->curr_active_slave was prematurely cleared to NULL when
releasing the backup slave, the subsequent iteration releasing the active slave evaluates oldcurrent as
NULL, so bond_change_active_slave(bond, NULL) is skipped. Consequently, bond_alb_handle_active_change() is
never called to decrement the promiscuity counter, permanently leaking promiscuous mode on the physical
device after bond teardown. When oldcurrent == slave, bond_change_active_slave(bond, NULL) already sets
bond->curr_active_slave to NULL. We only need to avoid selecting a new active slave when all == true.
Replace the if (all) branch with if (!all && oldcurrent == slave). (CVE-2026-98074)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
