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: ipvs: stop estimator after disabled
calc phase IPVS estimator kthread 0 starts with zeroed chain and tick limits until its initial calculation
phase completes. If network namespace teardown clears ipvs->enable during that phase,
ip_vs_est_calc_phase() can return without installing positive limits. The kthread can then continue into
its main loop and drain est_temp_list with zero chain_max, tick_max and est_max_count values. Each enqueue
consumes one available tick row, but est_count never reaches the zero est_max_count value. After all rows
are consumed, the row lookup returns IPVS_EST_NTICKS and ip_vs_enqueue_estimator() writes past the ticks
and tick_len arrays. Exit kthread 0 after the calculation phase if the kthread is stopping or IPVS has
been disabled. That keeps temporary estimators from being drained after the limits failed to initialize.
Estimator kthreads can now self-exit before teardown or reload stops kd->task. Keep an extra task
reference after creation and release it with kthread_stop_put(), so kd->task remains valid until the stop
paths consume that reference. (CVE-2026-74670)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.731.2 or later.
