Background for this topic.
A flaw is a defect in software, hardware, system design, or configuration that causes unintended behavior. In security reporting, the term usually means a weakness that could violate confidentiality, integrity, or availability when reached through a particular interface, input, privilege, or operating condition. Not every flaw is exploitable, and exploitability depends on factors such as exposure, authentication requirements, affected versions, and available mitigations.
Flaws matter because they can create attack paths in applications, operating systems, devices, APIs, or administrative settings. Security teams assess their severity and exposure, prioritize remediation, apply patches or configuration changes, and use isolation or access controls when immediate fixes are unavailable. Code review, testing, vulnerability scanning, and monitoring can reveal flaws across the development and operational lifecycle. Reports should distinguish a confirmed vulnerability from a theoretical defect and provide enough technical detail to support validation without unnecessarily enabling exploitation.
An advanced China-nexus cyber espionage group previously linked to the exploitation of security flaws in VMware and Fortinet appliances has been linked to the abuse of a critical vulnerability in VMware vCenter Server as a zero-day since late 2021
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday issued an emergency directive urging Federal Civilian Executive Branch (FCEB) agencies to implement mitigations against two actively exploited zero-day flaws in Ivanti Connect Secure (ICS) and Ivanti Policy Secure (IPS) products
CISA issued this year's first emergency directive ordering Federal Civilian Executive Branch (FCEB) agencies to immediately mitigate two Ivanti Connect Secure and Ivanti Policy Secure zero-day flaws in response to widespread and active exploitation by multiple threat actors. [...]
VMware has confirmed that a critical vCenter Server remote code execution vulnerability patched in October is now under active exploitation. [...]
LeftoverLocals Affects Apple, AMD and Qualcomm DevicesResearchers uncovered a critical vulnerability in graphic processing units of popular devices that could allow attackers to access data from large language models. They dubbed the vulnerability LeftoverLocals and said it affects the GPU frameworks of Apple, AMD and Qualcomm devices.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a now-patched critical flaw impacting Ivanti Endpoint Manager Mobile (EPMM) and MobileIron Core to its Known Exploited Vulnerabilities (KEV) catalog, stating it's being actively exploited in the wild

Continuous integration and continuous delivery (CI/CD) misconfigurations discovered in the open-source TensorFlow machine learning framework could have been exploited to orchestrate supply chain attacks
Multiple security vulnerabilities have been disclosed in the TCP/IP network protocol stack of an open-source reference implementation of the Unified Extensible Firmware Interface (UEFI) specification used widely in modern computers
So much for isolation A design flaw in GPU drivers made by Apple, Qualcomm, AMD, and likely Imagination can be exploited by miscreants on a shared system to snoop on fellow users.…
Citrix NetScaler ADC and Gateway Bugs Exploited in the WildIT infrastructure mainstays including Netscaler, Atlassain and VMWare on Tuesday released fixes for vulnerabilities including some allowing malicious takeover of appliances. NetScaler warned customers Tuesday of two zero day vulnerabilities that researchers say are being exploited in the wild.
Google Fixes Out-of-Bounds Memory Access Flaw, Microsoft Edge Browser Also AffectedGoogle released an urgent fix for the first zero-day vulnerability of the year in its Chrome web browser, warning the bug is under active exploitation. Google blamed an out-of-bounds memory access flaw in its V8 JavaScript rendering engine. It also affects Microsoft Edge browser.
The point-of-sale (PoS) terminals from PAX Technology are impacted by a collection of high-severity vulnerabilities that can be weaponized by threat actors to execute arbitrary code
Citrix is warning of two zero-day security vulnerabilities in NetScaler ADC (formerly Citrix ADC) and NetScaler Gateway (formerly Citrix Gateway) that are being actively exploited in the wild
Google on Tuesday released updates to fix four security issues in its Chrome browser, including an actively exploited zero-day flaw
GitHub rotated keys potentially exposed by a vulnerability patched in December that could let attackers access credentials within production containers via environment variables. [...]
You didn't have anything else to do this Tuesday, right? VMware and Atlassian today disclosed critical vulnerabilities and, while neither appear to have been exploited by miscreants yet, admins should patch now to avoid disappointment.…
