Description

The remote Fedora 37 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-3661f028b8 advisory.

 - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)
