Since if_id can be any 16-bit value (0-65535) but the ports\narray is only allocated with sw_attr.num_ifs elements, this can lead to\nan out-of-bounds read potentially.\n\nAdd a bounds check before accessing the array, consistent with the\nexisting validation in dpaa2_switch_rx().","state":0,"publishedAt":"2026-02-14T16:27:11.463+00:00","modifiedAt":"2026-10-19T18:25:34.438+00:00","affected":[{"ecosystem":"Vendor
