In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: do not allow SET_ID to refer to another table
When doing lookups for sets on the same batch by using its ID, a set from a different table can be used.
Then, when the table is removed, a reference to the set may be kept after the set is freed, leading to a potential use-after-free.
When looking for sets by ID, use the table that was used for the lookup by name, and only return sets belonging to that same table.
This fixes CVE-2022-2586, also reported as ZDI-CAN-17470.
