Description

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.

Affected configurations

• linux linux kernel (>= 3.16 < 4.19.256) • linux linux kernel (>= 4.20 < 5.4.211) • linux linux kernel (>= 5.5 < 5.10.137) • linux linux kernel (>= 5.11 < 5.15.61) • linux linux kernel (>= 5.16 < 5.18.18) • linux linux kernel (>= 5.19 < 5.19.2)
