The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: goku_udc: avoid NULL deref of dev->driver in INT_USBRESET log
goku_irq() handles a number of bus events under a single ep0 path. It already guards the gadget driver suspend/resume callbacks against a NULL ->driver:
if (dev->gadget.speed != USB_SPEED_UNKNOWN
&& dev->driver
&& dev->driver->resume) {
spin_unlock(&dev->lock);
dev->driver->resume(&dev->gadget);
...
}
but the very next branch unconditionally dereferences dev->driver when an INT_USBRESET arrives:
if (stat & INT_USBRESET) {
ACK(INT_USBRESET);
INFO(dev, "USB reset done, gadget %s\n",
dev->driver->driver.name);
}
If the controller raises INT_USBRESET before any gadget driver has been bound (or after one has been unbound), dev->driver is NULL and the printk dereferences NULL.
smatch flags the inconsistency:
drivers/usb/gadget/udc/goku_udc.c:1618 goku_irq() error: we previously assumed 'dev->driver' could be null (see line 1607)
Fall back to a placeholder when the gadget driver is not bound.
No functional change while a gadget driver is bound.
