high Tenable Cloud Security Plugin ID 469459

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_tables: make nft_object
rhltable per table The nft_object rhltable is global, this allows for accessing objects that are being
dismangled from lookup path by other existing netns. Given the nft_obj_destroy() releases the object
inmediately, this might lead to use-after-free of these objects that are being released. Make the existing
rhltable per table to address this issue to deal with with the nft_rcv_nl_event() path too. Update
nft_obj_lookup() to take the table as non-const, otherwise, compiler complains when passing the objname_ht
to rhltable_lookup(). (CVE-2026-74565)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
