The "Randomized slab caches for kmalloc()" patch was merged into mainline. With CONFIG_RANDOM_KMALLOC_CACHES=y, each kmalloc cache is split into 16. kmalloc uses a random one for each allocation based on the code location. Choices change every reboot. https://t.co/EoSYZxc8gI

📏 This value is 15 bytes less than the L2CAP MTU 0x69B (1,691) in relation with BNEP. We're digging deeper to understand the implications of this change. ⚙️🔬 #L2CAP #MTU

🔧 The BnepBookmarkIncomingPacket() function seems to be involved. An additional check is now performed before entering a while loop to ensure that r14_2 <= 0x68c (1,676). 📝🔐 #FunctionAnalysis

🔍 Preliminary findings suggest the vulnerability may be related to a patch in the bthpan.sys kernel driver, responsible for Bluetooth Personal Area Network. 🌐💻 #BthpanSys #KernelDriver

🚨 Early info on CVE-2023-28227: Windows Bluetooth RCE! 🧐 We're working hard to analyze the patch and pinpoint the bug. Stay tuned for updates! #CVE2023 #BluetoothRCE #WindowsSecurity

🎯 By doing so, organizations can identify and patch similar vulnerabilities within their products, enhancing their product security posture and staying ahead of adversaries. ⚔️🛡️ #StayAhead #RobustSecurity

✅ While this is great for researchers, businesses should also adopt a proactive approach by performing variant and root cause analysis internally before vulnerabilities are disclosed publicly. 🛡️🔍 #ProactiveSecurity

📚 From firsthand experience in responsible disclosure, We have seen researchers race to perform root cause and variant analysis on newly discovered vulnerabilities. Their goal? To find variants and submit them to bug bounty programs. 🏃‍♂️💰 #BugBounty #ResponsibleDisclosure

🚀 Have you considered the power of variant analysis in product security? It's time to dive into the benefits of this often-underestimated approach. 🧐💡 #ProductSecurity #VariantAnalysis

📈 Vulnerability research is a journey, and staying informed is key. Keep learning, and you'll become a more effective researcher, contributing to the security of large, complex systems. 🏆 #StayInformed #VulnerabilityResearchSuccess

📚 Keep learning and updating your knowledge of attack vectors, coding patterns, and best practices. This will help you better identify potential issues and improve your vulnerability hunting strategy. 🧠 #ContinuousLearning #SecurityExpertise

🔧 Another tip is to automate your process as much as possible. Use tools that help you track, identify, and record these functions. This way, you can keep an eye on potential security risks that might arise from human error in future updates. 🛠️ #Automation #SecurityTools

🕵️‍♂️ When auditing code, don't dismiss non-exploitable bugs. Keep detailed notes on them, and monitor the areas of code where they occur. This vigilance will help you spot when a developer forgets to properly check the return value or input args. 🔍 #CodeAudit #SecurityAwareness

📝 It's crucial to keep track of those functions where the caller is responsible for handling checks before and after the given function call. Why? Because developers are human, and mistakes can happen! 🙌 #DeveloperMistakes #InsecureCode

🚀 Getting started with vulnerability research on large, complex targets can be daunting. But what do you do with non-exploitable bugs found within simple routines that return a size value, where the caller is responsible for verification? 🧐 #BugHunting #VulnerabilityResearch
