Description Ganesh 2026-10-14 15:56:28 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A flaw was found in DPDK lib/vhost. The vhost log mapping calculation applies the mmap offset twice, which can lead to incorrect memory access.
