Threat Intelligence
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.

CVE-2026-68400 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_ffa: Fix Endpoint Memory Access Descriptor offset calculation
Use the descriptor's ep_mem_offset to calculate the start of the endpoint
memory access array and to comply with the FF-A spec instead of defaulting
to sizeof(struct ffa_mem_region).
This requires moving ffa_mem_region_additional_setup() earlier in the setup
flow.
Also, add sanity checks to ensure the calculated descriptor offsets do not
exceed max_fragsize.
