Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference when the NFTA_INNER_NUM and NFTA_EXPR_NAME netlink attributes are accessed. An attacker can crash the system or escalate their privileges on the system by exploiting the lack of presence checks in nft_inner.c.

Note:

This is only exploitable if the user has local access to the system.
