[SeaBIOS] Uninitialized local leads to undefined memory dereference

[Datta manikanta sri hari Danduri]

Hi

ISSUE-1:

seabios-1.15.0/scripts/kconfig/menu.c

function get_prompt_str, the variable jump is uninitialized and may lead to illegal access at

if (i > 0) {

str_printf(r, _("  Location:\n"));

for (j = 4; --i >= 0; j += 2) {

menu = submenu[i];

if (head && location && menu == location)

jump->offset = strlen(r->s);

str_printf(r, "%*c-> %s", j, ' ',

_(menu_get_prompt(menu)));

if (menu->sym) {

str_printf(r, " (%s [=%s])", menu->sym->name ?

menu->sym->name : _("<choice>"),

sym_get_string_value(menu->sym));

}

str_append(r, "\n");

}

}

ISSUE-2:

seabios-1.15.0/src/hw/usb-ohci.c

function start_ohci, the check is incorrect

for (;;) {

u32 status = readl(&cntl->regs->cmdstatus);

if (! status & OHCI_HCR)

break;

if (timer_check(end)) {

warn_timeout();

return -1;

}

}

Thanks
