An unprivileged Linux program can time a hardware interrupt to land in the gap between a processor sanitizing its branch predictor and the kernel using it, re-poisoning the predictor after the defense has run.

MIT CSAIL researchers Daniël Trujillo and Mengjia Yan named the technique INTERRUPT INJECTION. On an AMD Zen 2 machine running Linux 6.14 with every default Spectre v2 mitigation on,

Cisco has rolled out updates to address multiple critical security vulnerabilities impacting Catalyst SD-WAN and IOS XE Software as part of a comprehensive internal security review.

The security issues affect Cisco Catalyst SD-WAN Software, regardless of device configuration, and Cisco IOS XE Software when it is running in autonomous or controller mode.

“These vulnerabilities were found

Zapscape, a new Linux kernel vulnerability, could allow an attacker with kernel privileges inside an L1 guest virtual machine (VM) to escape KVM isolation and execute code on the host. The risk applies when nested virtualization is exposed to untrusted guests.

The flaw is tracked as CVE-2026-64561 and affects KVM/x86’s shadow memory management unit (MMU), which manages shadow page

A federal judge in Alexandria, Virginia, sentenced Maksim Silnikau to 16 years in prison on August 5 for creating and running Ransom Cartel, the ransomware-as-a-service operation he stood up in 2021.

Between 2021 and 2023, Ransom Cartel conspirators attacked at least 18 companies, including firms in California, New York and Nebraska, and others abroad, according to the Justice Department.

Cybersecurity researchers have disclosed details of a “factory-shipped backdoor” implanted in at least 20 Chinese router models from Zbtlink.

According to a new report from VulnCheck, the implant appears in all 21 firmware images currently available from Zbtlink that span more than 2 years. The backdoors are designed such that they start automatically and attempt to beacon to Chinese

Security flaws in agent infrastructure from Amazon Web Services (AWS), Google, and Vercel let untrusted or forged instructions reach an agent’s tools with no check that a model turn had authorized them.

In several of the attack paths, the model never ran at all, so system prompts, content filters, and model-level guardrails never got a chance to intervene.

The affected products include Amazon

Attackers broke into an organization’s Oracle database through a SQL injection flaw in a public-facing web application, then installed a post-exploitation toolkit without writing an executable to disk. They fed Java source code to the database, let Oracle compile it into stored schema objects, and ran commands from inside the database engine.

Huntress, which tracks the toolkit as khunt,

Patches were rolled out for two dozen vulnerabilities, including one with public proof-of-concept (PoC) code.
