Security Researchers Fear Broader Legal Pressure on Bug DisclosuresMicrosoft is pursuing legal action after a researcher publicly released six Windows zero-days and exploit code following a breakdown in coordinated disclosure talks, escalating tensions over vulnerability disclosure, platform moderation and protections for independent security researchers.

Microsoft has come out strongly in favor of Coordinated Vulnerability Disclosure (CVD), urging the research community to share their findings and give affected vendors an opportunity to better understand the impact and address them before they are publicly disclosed

1 Introduction This article provides a technical analysis of how many Windows kernel mode drivers can be interacted with from user mode without the hardware they were developed for. This work was motivated by driver-oriented vulnerability research and the need to evaluate the exploitability of individual findings, which frequently affect code whose reachability is hardware-gated. The

The high volume of vulnerabilities reflects a growing trend researchers have been anticipating as artificial intelligence models are deployed to find previously uncovered defects in code. The post Microsoft addresses 137 vulnerabilities in May’s Patch Tuesday, including 13 rated critical appeared first on CyberScoop.
