medium Tenable Cloud Security Plugin ID 475558

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: nft_nat: fully initialise
 new_addr in netmap setup nft_nat_setup_netmap() builds the mapped address in an on-stack union
 nf_inet_addr. For an IPv4 mapping it writes only the 4-byte .ip member and the loop runs a single 32-bit
 iteration, but it then copies the whole 16-byte union into range->min_addr and range->max_addr, so the
 upper 12 bytes reach nf_nat_setup_info() uninitialised. KMSAN reports an uninit-value in
 nf_nat_setup_info() reached from nft_nat_eval(). The IPv6 path fills all 16 bytes and is not affected.
 Zero-initialise new_addr. (CVE-2026-98322)

Solution

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