📢 Last week, Brown Secure Systems Lab (SSL, https://gitlab.com/brown-ssl/) was at the IEEE Symposium on Security and Privacy (S&P) 2025, where we presented our latest work on hardening OS kernels against attacks that (ab)use heap-based memory-safety vulnerabilities. #IUBIK leverages memory tagging (MTE) and pointer authentication (PA), available in #ARM CPUs, to efficiently and effectively isolate attacker-controlled input from security-critical data in the kernel heap.
👏 Kudos to Marius Momeu (leading author) who did a terrific job presenting our paper -- joint work with Alexander Gaidis (Brown University) and Jasper von der Heidt (Technical University of Munich).
