CWE ID 476
Summary
CVE-2022-49582 is a vulnerability affecting the Linux kernel where a NULL pointer dereference occurs in the function dsa_port_reset_vlan_filtering. The issue stems from the use of the same iterator variable "ds" for both dsa_switch_for_each_port() and the argument "dp" passed to dsa_port_vlan_filtering(). Consequently, switches with vlan_filtering_is_global=true will dereference an invalid dp pointer upon exiting a VLAN-aware bridge. To mitigate this issue, a new iterator variable "other_dp" should be used instead.
