Two CVSS 9.0 Linux KSMBD RCE Flaws Disclosed on Public Mailing Lists Before Kernel Fixes

Two CVSS 9.0 Linux KSMBD RCE Flaws Disclosed on Public Mailing Lists Before Kernel Fixes

Oct 22, 2026 Vulnerability / Linux
Linux servers running KSMBD, the kernel's built-in SMB server, are exposed to two publicly reported remote code execution flaws rated 9.0 by  Trend Micro's Zero Day Initiative , with no fix yet in the mainline kernel. One of them, ZDI-CAN-33774, can be triggered before any network authentication. The other, ZDI-CAN-33549, requires the SMB Direct transport and an RDMA-capable network interface. ZDI-CAN-33549  is an integer underflow in KSMBD's SMB Direct path. A client can supply RDMA buffer descriptors in which the first is longer than the declared payload, causing the server's size counter to wrap and allowing a subsequent memory copy to overrun the end of an allocated buffer. It requires three things: an RDMA-capable interface (hardware or the rxe software driver), a writable KSMBD share, and a client negotiating SMB Direct. ZDI-CAN-33774  requires no authentication, exposing any server running KSMBD on port 445. The flaw is a race in how KSMBD assign...
Meta Ordered to Pay $25 Billion After Court Finds 43 Million Privacy Violations

Meta Ordered to Pay $25 Billion After Court Finds 43 Million Privacy Violations

Oct 22, 2026 Data Privacy / Regulatory
Social media giant Meta was ordered to pay 25 billion in penalties by a New Mexico court on Wednesday as part of a data privacy lawsuit that sprang from the company's Cambridge Analytica data scandal , which came to light in 2018. According to multiple reports from the Associated Press , the New York Times , Reuters , and the Wall Street Journal , state District Court Judge Francis J. Mathew called out Meta and Facebook for making misleading statements about the privacy of consumers in the state. "Facebook promised users that they (the users) controlled their data," Mathew wrote in his ruling. "This was false." The penalty relates to more than 43 million violations of the state's unfair practices law. The case, filed in 2021, was filed in the aftermath of revelations that Cambridge Analytica, a British political consulting firm, obtained data belonging to millions of Facebook users without their consent to build psychographic profiles. The data was ...
INTERPOL Arrests 1,462 Suspects, Disrupts 10,909 Cybercrime Networks in Global Crackdown

INTERPOL Arrests 1,462 Suspects, Disrupts 10,909 Cybercrime Networks in Global Crackdown

Oct 22, 2026 Cybercrime / Law Enforcement
INTERPOL on Thursday announced that a coordinated law enforcement action has disrupted 10,909 malicious networks and recovered more than $105 million in illicit funds. In tandem, the effort saw law enforcement agencies from 21 countries arrest 1,462 suspects. Codenamed Operation Serengeti III , the cybercrime crackdown took place between June 29 and August 31, 2026. "Authorities identified 65,929 victims targeted by cybercriminal networks, underscoring the scale and sophistication of today's digital threats," INTERPOL said in a statement. "Financial investigations linked criminal activity to losses exceeding USD 385 million."

Railway Says Intruder May Have Accessed Customer Secrets, Urges Credential Rotation

Railway Says Intruder May Have Accessed Customer Secrets, Urges Credential Rotation

Oct 22, 2026 Cloud Security / Artificial Intelligence
Platform-as-a-Service (PaaS) provider Railway on Wednesday disclosed "anomalous activity" related to systems that store customer environment variables. Upon further investigation, the company found that an unauthorized third party may have gained access to encrypted environment variables, and, in some cases, obtained the decrypted contents. The impact, it said, is limited to a "subset of users," although it did not disclose an exact number. Environment variables refer to user-defined key-value pairs that are used to store sensitive data like API keys, database credentials, or feature flags. They are configured at the operating system or container environment level instead of hard-coding the values directly into a program's source code. Railway said the incident is likely part of a series of attacks designed to target platform companies with the ultimate goal of compromising artificial intelligence (AI) inference providers. The company also said it has n...
OpenCode Flaw Lets Malicious MCP Servers Execute Code During Sign-In on Windows and WSL

OpenCode Flaw Lets Malicious MCP Servers Execute Code During Sign-In on Windows and WSL

Oct 22, 2026 Vulnerability / Artificial Intelligence
A flaw in the OpenCode AI coding agent allowed a malicious or hijacked MCP server to run code on a developer's Windows or WSL machine when the developer signed in. OpenCode connects to MCP (Model Context Protocol) servers to add outside tools, and such code would run with the developer's own access. Anomaly , the company behind OpenCode, fixed the flaw in  version 1.18.33  on September 28. It did not request a CVE or publish a security advisory, so vulnerability scanners will not flag the builds still at risk: 1.0.137 through 1.18.32. During that sign-in, the server itself supplies the web address the user is sent to, an OAuth "authorization endpoint." On Windows and WSL, OpenCode handed that address to a helper that opens it in a browser. The helper built a PowerShell command around the address without escaping it, so an address written to carry a PowerShell command would run that command. The browser step runs only when a developer starts the sign-in, by ru...
LiteLLM Suspects GitHub Token Leak in AI Gateway Logs Behind Malicious Package Release

LiteLLM Suspects GitHub Token Leak in AI Gateway Logs Behind Malicious Package Release

Oct 22, 2026 Cloud Security / Data Breach
LiteLLM on Wednesday disclosed that threat actors compromised "multiple independent security controls" to push a malicious version of the Python package containing a credential stealer and a backdoor. On October 21, 2026, LiteLLM's release pipeline was compromised to push 1.107.0 to the Docker Hub registry and the Python Package Index (PyPI) repository. The incident took place around 4:00 a.m. PST. The following compromised versions were published - LiteLLM v1.107.0 (PyPI) v1.107.0, latest, main-latest, and main-stable (Docker) v1.107.0, latest, main-latest, and main-stable (GHCR) Users who downloaded an unpinned version of LiteLLM between 11:39 a.m. and 1:23 p.m. UTC via pip or used the Docker image v1.107.0, latest, main-latest, or main-stable between 11:46 a.m. and 2:20 p.m. UTC are impacted. The poisoned version incorporated code to harvest credentials and keys, and run arbitrary code from a remote server every hour, turning it into a remote acce...
Node.js Brotli Decoder Bug Could Allow Remote Code Execution in All Supported Versions

Node.js Brotli Decoder Bug Could Allow Remote Code Execution in All Supported Versions

Oct 22, 2026 Vulnerability / Web Security
Node.js released  security updates  on October 21 for its three supported release lines, 22.x, 24.x and 26.x, fixing 10 flaws. The most serious is a bug in the Brotli decompression code that Node.js bundles, which the project says can allow remote code execution, meaning an attacker could run code of their choosing on the affected system. Each supported line has one fixed version:  22.23.4  and  24.22.1  on the long-term support lines, and  26.12.1  on the current line. Node.js 20.x and earlier have  reached end of life  and will not receive the fix, so they should be moved to a supported line. The Brotli flaw is in code Node.js bundles, not in a user's own program. Node.js runs that code whenever it decompresses Brotli data, either directly through the  node:zlib  module or automatically when code calls fetch() on a response sent with Brotli compression. An application is exposed where it decompresses Brotli data an att...
