UBUNTU-CVE-2026-53223

In the Linux kernel, the following vulnerability has been resolved: net: guard timestamp cmsgs to real error queue skbs skbiserrqueue treats PACKETOUTGOING as the sole marker for an skb from skerrorqueue. That assumption is not true for AFPACKET sockets: outgoing packet taps are also delivered to...

CVE-2026-53235

Summary of technical details (CVE-2026-53235) : The Linux kernel GRO receive path had a bug in skb_gro_receive_list() where skb_pull(skb, skb_gro_offset(skb)) could run without ensuring the data is linear (missing pskb_may_pull() guard). When packets arrive via napi_gro_frags(), skb_headlen can b...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: vsock/virtio: Only linear skb values are coalesced. In vsock/virtio common, attempts to coalesce buffers in the rx queue: if a linear skb with a spare tail room is followed by a small skb whose length is limited by GOODCOPYLEN...

GHSA-CGXM-VR2F-6FJ8 parse-server: Denial of service via exponential-time processing of deeply nested query operators

Impact Parse Server is vulnerable to denial of service. A remote attacker can send a single, small query 1 KB containing deeply nested query condition operators. Parse Server processes the nested structure with exponential time complexity, which blocks the Node.js event loop and makes the server...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: vsock/virtio: fixed an issue where an empty payload was present in the tap skb for non-linear buffers. For non-linear skbs, virtiotransportbuildskb calls virtiotransportcopynonlinearskb to copy the original payload into a new...

GHSA-X92V-RPX6-P6CW PraisonAI: Webhook signature verification skipped (fail-open) when secret unset, allowing forged inbound webhooks (WhatsApp & Linear bots)

The WhatsApp and Linear bot adapters verify the inbound webhook HMAC signature only when a secret is configured. When the secret environment variable is unset — the default on a fresh install and common in development — verification is skipped entirely and the webhook body is parsed and dispatche...

Smarter Saboteurs, Better Fixers: Scaling and Security in Linear Multi-Agent Workflows

As LLM-based multi-agent systems MAS are deployed in the wild, the resilience of their collaboration structures against adversarial compromise becomes a critical safety concern. Attackers may leverage prompt-injection or jailbreaking to sabotage individual agents within MAS workflows, but the...

golang: archive/zip: Excessive CPU consumption when building archive index in archive/zip

A flaw was found in the archive/zip package in the Go standard library. A super-linear file name indexing algorithm is used in the first time a file in an archive is opened. A crafted zip archive containing a specific arrangement of file names can cause an excessive CPU and memory consumption. A ...

Dimensionality Reduction for Cyberattack Classification: A Comparative Evaluation of PCA and Linear Predictive Coding

High-dimensional feature representations are widely used in machine learning-based cyberattack detection systems. However, they increase computational complexity and may hinder deployment in resource-constrained environments. In this paper, we investigate feature compression techniques for...

SUSE CVE-2026-46207

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix empty payload in tap skb for non-linear buffers For non-linear skbs, virtiotransportbuildskb goes through virtiotransportcopynonlinearskb to copy the original payload in the new skb to be delivered to the vsockm...

CVE-2026-46207

A flaw was found in the Linux kernel's vsock/virtio component. When processing non-linear data buffers for the vsockmon tap device, the system did not correctly initialize the payload. This oversight could lead to uninitialized data being copied to the monitoring interface, potentially resulting ...
