9-Year-Old Linux Kernel Flaw Enables Root Command Execution on Major Distros

Cybersecurity researchers have disclosed details of a vulnerability in the Linux kernel that remained undetected for nine years.

The vulnerability, tracked as CVE-2026–46333 (CVSS score: 5.5), is a case of improper privilege management that could permit an unprivileged local user to disclose sensitive files and execute arbitrary commands as root on default installations of several major distributions like Debian, Fedora, and Ubuntu. It’s also codenamed ssh-keysign-pwn.

According to Qualys, which discovered the flaw, the problem is rooted in the kernel’s __ptrace_may_access function and was introduced in November 2016.

Highly Critical Drupal Core Flaw Exposes PostgreSQL Sites to RCE Attacks

Drupal has released security updates for a “highly critical” security vulnerability in Drupal Core that could be exploited by attackers to achieve remote code execution, privilege escalation, or information disclosure.

The vulnerability, now tracked as CVE-2026–9082, carries a CVSS score of 6.5 out of 10.0, per CVE.org. Drupal said the vulnerability resides in a database abstraction API that is used in Drupal Core to validate queries and ensure they are sanitized against SQL injection attacks.

“A vulnerability in this API allows an attacker to send specially crafted requests, resulting in arbitrary SQL injection for sites using PostgreSQL databases,” it said. “This can lead to information disclosure, and in some cases privilege escalation, remote code execution, or other attacks.”

Scientists reversed memory loss by recharging the brain’s tiny engines

Researchers have shown for the first time that malfunctioning mitochondria — the cell’s energy generators — may directly cause cognitive decline in neurodegenerative diseases. By creating a new tool that temporarily boosts mitochondrial activity in the brain, scientists restored memory performance in mouse models of dementia. The discovery hints that energy failure inside neurons could happen before brain cells die, potentially offering a new target for future Alzheimer’s treatments.

How schizophrenia risk may begin: Gene changes reshape signaling in developing neurons

Researchers at King’s College London have identified the biological nature and timing of changes in human cortical neurons caused by altering activity of a schizophrenia-associated gene in developing human neurons. This discovery links a genetic risk factor to cellular changes in neurons; an essential step for understanding the neurobiology of this mental illness and developing future treatments.

Schizophrenia is estimated to be one of the most heritable psychiatric conditions, with a strong developmental aspect. Large-scale human genomic studies have identified many genetic variants which are thought to increase the likelihood of schizophrenia.

However, the link between these genetic risk variants and the underlying neurobiology of schizophrenia is less well understood. Addressing this knowledge gap provides vital information that could ultimately help develop therapies for the disorder.

Scientists use light to create tiny molecules that could transform medicine

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for drug development and materials science. These compact ring-shaped structures are difficult to produce because of the intense internal strain they contain. By using photocatalysis and carefully tuning the starting molecules, the team managed to guide the reaction into a clean and efficient pathway.
