CVE-2021-46283 is fixed in linux on 1 platform, first by DEBIAN-CVE-2021-46283, released January 11, 2022. It is not reported as exploited. Patch Radar priority: Routine.
nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace.
