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: eth: ice: don't dereference pointers
from TP_printk() After forwarding net-next during the v7.3 merge window we started seeing: TRACE EVENT
ERROR: Event ice_tx_dim_work has double dereference in TP_printk: REC->q_vector->tx.tx_ring->q_index
WARNING: kernel/trace/trace_events.c:420 at test_double_dereference.cold+0x39/0x4b this is due to extra
checks added in tracing subsystem in commit b5cc230af5e5 ("tracing: Warn when an event dereferences a
pointer in TP_printk()"). Printing happens long after the event was recorded, by which point the pointers
may be invalid (the ring or the dim instance). Copy the eight scalars into the event instead.
(CVE-2026-97978)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20198.0.0 or later.
