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: netfilter: nf_flow_table: drop
 existing skb dst before skb_dst_set_noref() Incoming skbs passing through netfilter flowtable offload
 hooks (or XFRM offload path) might already carry a ref-counted dst_entry assigned during earlier RX or
 routing steps. Calling skb_dst_set_noref() when skb already holds a ref-counted dst overwrites
 skb->_skb_refdst, leaking the previous dst_entry reference count and triggering a DEBUG_NET_WARN_ON_ONCE
 assertion in skb_dst_check_unset(): WARNING: at skb_dst_check_unset include/linux/skbuff.h:1170 WARNING:
 at skb_dst_set_noref include/linux/skbuff.h:1234 WARNING: at nf_flow_offload_ip_hook+0xf6c/0x2b60
 net/netfilter/nf_flow_table_ip.c:864 Drop any existing dst_entry reference with skb_dst_drop(skb) before
 setting the non-referenced flowtable destination. (CVE-2026-74695)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20085.0.0 or later.
