Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

Incorrect verifier pruning in the BPF module of the Linux kernel version 5.4 and above leads to unsafe code paths being incorrectly marked as safe. This results in arbitrary read/writes to kernel memory, lateral privilege escalation, and container escapes...

The Model Proposes, the Code Disposes: A Pre-Registered Ablation of a Verifier-And-Acceptance Stage in an LLM-Orchestrated Offensive-Security Agent

We evaluate whether a verifier-and-acceptance stage - a model verifier whose verdicts are enforced by deterministic code - changes what an LLM-driven offensive-security agent reports. We report a 15-run exploratory pilot, a pre-registered 20-run confirmatory ablation, and a pre-registered 2 x 2...

Linux Distros Unpatched Vulnerability : CVE-2026-89706

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nfsd: Reset write verifier when async COPY writeback fails Async COPY captures nn-writeverf at request time and reports it to the client via CBOFFLOAD after the...

CVE-2026-89706

A flaw was found in the Linux kernel's nfsd component. When an asynchronous async copy writeback operation fails, the server's write verifier is not properly reset. This can lead to a client incorrectly assuming that data has been made durable, resulting in the silent loss of data that was intend...

CVE-2026-89706

A vulnerability in the Linux kernel's nfsd (NFS server) component causes silent data loss during asynchronous COPY operations. When post-copy writeback fails (via vfs_fsync_range() or filemap_check_wb_err()), the server correctly reports NFS_UNSTABLE but fails to rotate the write verifier. The cl...
