Detailed vulnerability description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a type confusion error within the nft_lookup_init() function in net/netfilter/nft_lookup.c, within the nf_tables_fill_setelem() and nft_validate_register_store() functions in net/netfilter/nf_tables_api.c. A local user can pass specially crafted data to the packet filtering to trigger a type confusion error and gain access to sensitive information.
