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:
mmc: davinci: avoid NULL deref of host->data in IRQ handler
mmc_davinci_irq() returns early only when both host->cmd and host->data are NULL:
if (host->cmd == NULL && host->data == NULL) { ... return IRQ_NONE; }
So we may legitimately reach the rest of the handler with host->data == NULL (and therefore data == NULL). The DATDNE branch already guards against this with an explicit "if (data != NULL)" check, but the subsequent TOUTRD ("read data timeout") and CRCWR/CRCRD ("data CRC error") branches dereference data unconditionally:
if (qstatus & MMCST0_TOUTRD) { data->error = -ETIMEDOUT; <-- NULL deref ... davinci_abort_data(host, data); }
if (qstatus & (MMCST0_CRCWR | MMCST0_CRCRD)) { data->error = -EILSEQ; <-- NULL deref ... }
If either bit is set in qstatus while host->data is NULL, the kernel will crash inside the IRQ handler. smatch flags this:
drivers/mmc/host/davinci_mmc.c:933 mmc_davinci_irq() error: we previously assumed 'data' could be null (see line 914)
Gate both branches on a non-NULL data, matching the existing pattern used by the DATDNE branch.
No functional change for callers where data is non-NULL, which is the only case in which these branches did meaningful work before this change.
