GHSA-PC6G-G5M7-F2GR

Vulnerability from github – Published: 2022-01-12 00:00 – Updated: 2022-01-21 00:01

Details

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.
