high Tenable Cloud Security Plugin ID 469467

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: nfnetlink_queue: make hash
table per queue Sharing a global hash table among all queues is tempting, but it can cause crash: BUG:
KASAN: slab-use-after-free in nfqnl_recv_verdict+0x11ac/0x15e0 [nfnetlink_queue] [..]
nfqnl_recv_verdict+0x11ac/0x15e0 [nfnetlink_queue] nfnetlink_rcv_msg+0x46a/0x930
kmem_cache_alloc_node_noprof+0x11e/0x450 struct nf_queue_entry is freed via kfree, but parallel cpu can
still encounter such an nf_queue_entry when walking the list. Alternative fix is to free the
nf_queue_entry via kfree_rcu() instead, but as we have to alloc/free for each skb this will cause more mem
pressure. (CVE-2026-43084)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.224.7 or later.
