Hi, I am part of a group developing a static analysis tool and we are running it on the latest linux kernel (5.7) to search for potential bugs. Our analysis has found a possible an kzalloc whose return is not checked in drivers/tty/vt/vt.c in the con_init function at line 3396. As I understand the following code: for (currcons = 0; currcons < MIN_NR_CONSOLES; currcons++) { vc_cons[currcons].d = vc = kzalloc(sizeof(struct vc_data), GFP_NOWAIT); INIT_WORK(&vc_cons[currcons].SAK_work, vc_SAK); tty_port_init(&vc->port); visual_init(vc, currcons, 1); vc->vc_screenbuf = kzalloc(vc->vc_screenbuf_size, GFP_NOWAIT); vc_init(vc, vc->vc_rows, vc->vc_cols, currcons || !vc->vc_sw->con_save_screen); } if kzalloc fails, vc->vc_screenbuf would be set to NULL and possibly dereferenced in the following code, namely when setting the origin (set_origin(vc)). Should there be a check on the kzalloc and an early termination if it fails to allocate?
