CVE-2026-74558

A flaw was found in the Linux kernel's zero-copy ZC transmit Tx batch path. When processing network packets, the system can fail to properly reclaim memory UMEM frames if it encounters invalid or oversized packet descriptors. This can lead to resource exhaustion, where memory is not returned to...

CVE-2026-72056

A flaw was found in the Linux kernel's Elastic Network Adapter ENA driver. During the setup of eXpress Data Path XDP transmit TX queues, if the subsequent setup of regular TX queues fails, the error handling mechanism does not properly clean up the XDP TX queues. This oversight can lead to a...
