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:
netfilter: nft_set_pipapo: fix stack out-of-bounds read in pipapo_drop()
pipapo_drop() passes rulemap[i + 1].n to pipapo_unmap() as the to_offset argument on every iteration, including the last one where i == m->field_count - 1. This reads one element past the end of the stack-allocated rulemap array (declared as rulemap[NFT_PIPAPO_MAX_FIELDS] with NFT_PIPAPO_MAX_FIELDS == 16).
Although pipapo_unmap() returns early when is_last is true without using the to_offset value, the argument is evaluated at the call site before the function body executes, making this a genuine out-of-bounds stack read confirmed by KASAN:
BUG: KASAN: stack-out-of-bounds in pipapo_drop+0x50c/0x57c [nf_tables] Read of size 4 at addr ffff8000810e71a4
This frame has 1 object: [32, 160) 'rulemap'
The buggy address is at offset 164 -- exactly 4 bytes past the end of the rulemap array.
Pass 0 instead of rulemap[i + 1].n on the last iteration to avoid the out-of-bounds read.
