The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2026:12176 advisory. cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves CVE-2026-26007 pyjwt: PyJWT accepts unknown crit header...

Formulating Subgroup Discovery As a Quantum Optimization Problem for Network Security

While current network intrusion detection systems achieve satisfactory accuracy, they often lack explainability. Subgroup Discovery SD addresses this by building interpretable rules that characterize feature interactions associated with attack traffic. With large datasets, classical heuristic bea...

SUSE CVE-2026-31434

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix leak of kobject name for sub-group spaceinfo When createspaceinfosubgroup allocates elements of spaceinfo-subgroup, kobjectinitandadd is called for each element via btrfssysfsaddspaceinfotype. However, when...

CVE-2026-31434

A flaw was found in the Linux kernel's btrfs filesystem. When sub-groups for space information are created, associated kobject names are allocated. However, these names are not properly released when the sub-groups are removed, leading to a memory leak. A local user could exploit this vulnerabili...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the exposure of the kobject name in the btrfs subgroup spaceinfo, potentially leading to memory...

Why Aggregate Accuracy Is Inadequate for Evaluating Fairness in Law Enforcement Facial Recognition Systems

Facial recognition systems are increasingly deployed in law enforcement and security contexts, where algorithmic decisions can carry significant societal consequences. Despite high reported accuracy, growing evidence demonstrates that such systems often exhibit uneven performance across demograph...
