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:
IB/hfi1: Fix leak of rcvhdrtail_dummy_kvaddr
This buffer is currently allocated in hfi1_init():
if (reinit) ret = init_after_reset(dd); else ret = loadtime_init(dd); if (ret) goto done;
/* allocate dummy tail memory for all receive contexts */ dd->rcvhdrtail_dummy_kvaddr = dma_alloc_coherent(&dd->pcidev->dev, sizeof(u64), &dd->rcvhdrtail_dummy_dma, GFP_KERNEL);
if (!dd->rcvhdrtail_dummy_kvaddr) { dd_dev_err(dd, "cannot allocate dummy tail memory\n"); ret = -ENOMEM; goto done; }
The reinit triggered path will overwrite the old allocation and leak it.
Fix by moving the allocation to hfi1_alloc_devdata() and the deallocation to hfi1_free_devdata().
