From Backlog Items to Security Guidance: Towards Continuous Security Compliance

Continuous software engineering in regulated domains requires engineering teams to address security throughout the development lifecycle. Yet making security requirements explicit in backlog items is still problematic. Engineers must instead infer security relevance of backlog items from brief,...

CVE-2026-64321

A flaw was found in the NVMe over RDMA nvmetrdma target in the Linux kernel. When a host queue backlog is exceeded during a connection attempt, a reference count kref is not properly released. This oversight can lead to a resource exhaustion vulnerability, potentially allowing a remote attacker t...

CVE-2026-64321

In the Linux kernel NVMe over RDMA target (nvmet_rdma), a kref reference on the returned ndev could be leaked when the host queue backlog is exceeded and NVME_SC_CONNECT_CTRL_BUSY is returned. The root cause is a missing release path in nvmet_rdma_queue_connect() that fails to kref_put() before t...

SUSE CVE-2026-64207

In the Linux kernel, the following vulnerability has been resolved: net/sched: dualpi2: fix GSO backlog accounting When DualPI2 splits a GSO skb into N segments, it propagates N additional packets to its parent before returning NETXMITSUCCESS. The parent then accounts for the original skb once...

CVE-2026-64207

A flaw was found in the Linux kernel's DualPI2 Dual-rate PI2 queue discipline. This vulnerability arises from incorrect accounting of Generic Segmentation Offload GSO backlog, where the parent queue such as QFQ - Hierarchical Fair Queueing miscalculates the number of queued packets. This...
