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.

In the Linux kernel, the following vulnerability has been resolved:
netfilter: nftables: exthdr: fix 4-byte stack OOB write
If priv->len is a multiple of 4, then dst[len / 4] can write past the destination array which leads to stack corruption.
This construct is necessary to clean the remainder of the register in case ->len is NOT a multiple of the register size, so make it conditional just like nft_payload.c does.
The bug was added in 4.1 cycle and then copied/inherited when tcp/sctp and ip option support was added.
Bug reported by Zero Day Initiative project (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961).
