Background for this topic.
Patch is a software, firmware, or configuration update that fixes a defect, including a vulnerability an attacker could use to gain access, execute code, escalate privileges, or expose data. Patching reduces the exploitable attack surface across operating systems, applications, network devices, and embedded systems; it does not remove risk from unsupported or misconfigured assets, and updates can sometimes introduce compatibility or availability problems.
Effective patch management starts with an accurate inventory and vulnerability assessment, then prioritizes internet-facing systems, high-impact assets, and flaws known to be exploited. Organizations should test updates where practical, deploy them within defined time limits, verify installation, and retain rollback or compensating controls when immediate patching is unsafe. Monitoring vendor advisories and threat intelligence can identify urgent fixes, while documenting exceptions and coverage supports vulnerability management and audit requirements.
Free unofficial security patches have been released through the 0patch platform to address a zero-day vulnerability introduced over two years ago in the Windows Mark of the Web (MotW) security mechanism. [...]
Researchers Discover 20 Critical Flaws Attackers Could Exploit in a Variety of WaysResearchers identified 20 critical vulnerabilities in a type of Advantech industrial-grade wireless access point that's widely deployed across critical infrastructure environments. Attackers could exploit the flaws to remotely executive code and create denials of service.
Nearly two dozen security vulnerabilities have been disclosed in Advantech EKI industrial-grade wireless access point devices, some of which could be weaponized to bypass authentication and execute code with elevated privileges
This vulnerability was patched in May 2024 but was only allocated a CVE in November after evidence of exploitation
A critical security flaw impacting the ProjectSend open-source file-sharing application has likely come under active exploitation in the wild, according to findings from VulnCheck
Exploits Could Allow Remote Command Execution and AccessThe Taiwanese NAS maker QNAP Systems on Saturday patched multiple flaws in its operating system and applications that could allow attackers to compromise network storage devices. The patch also included multiple flaws in QNAP's router operating system QuRouter OS.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a now-patched critical security flaw impacting Array Networks AG and vxAG secure access gateways to its Known Exploited Vulnerabilities (KEV) catalog following reports of active exploitation in the wild
