Description Deatils for the vulnerability is disucssed on confluence. This repo has been picked up after a few years on being dead, not looked at the DisabledSecurityManager code. TypeConfusionDemo OverflowDemo This is a demo that shows we can overflow into before the dst array. This demo works o...
Efficient Linkage-Based Compartmentalization on CHERI
We present an efficient linkage-based model for in-process compartmentalization built on CHERI memory safety, which enables fine-grained compartmentalization of the entire UNIX user-space, scaling to 10K+ compartments on desktop systems. The model's "push-button" compartmentalization along existi...
PRISM: Lightweight Enclave Isolation with Prismatic Capabilities
Trusted execution environments TEEs protect sensitive code and data from external interference, but lack inherent memory safety. CHERI can enforce spatial memory safety at the object level. Attempts to establish a TEE using CHERI primitives suffer from 1 expensive capability revocation operations...
CAPIO: Safe Kernel-Bypass of Commodity Devices Using Capabilities
Securing low-latency I/O in commodity systems forces a fundamental trade-off: rely on the kernel's high overhead mediated interface, or bypass it entirely, exposing sensitive hardware resources to userspace and creating new vulnerabilities. This dilemma stems from a hardware granularity mismatch:...
Biting the CHERI Bullet: Blockers, Enablers and Security Implications of CHERI in Defence
There is growing interest in securing the hardware foundations software stacks build upon. However, before making any investment decision, software and hardware supply chain stakeholders require evidence from realistic, multiple long-term studies of adoption. We present results from a 12 month...
cheri-cherie.fr Cross Site Scripting vulnerability OBB-3787094
Following the coordinated and responsible vulnerability disclosure guidelines of the ISO 29147 standard, Open Bug Bounty has: a. verified the vulnerability and confirmed its existence; b. notified the website operator about its existence. Technical details of the vulnerability are currently hidde...
What’s the smallest variety of CHERI?
The Portmeirion project is a collaboration between Microsoft Research Cambridge, Microsoft Security Response Center, and Azure Silicon Engineering & Solutions. Over the past year, we have been exploring how to scale the key ideas from CHERI down to tiny cores on the scale of the cheapest...

Security Analysis of CHERI ISA
Is it possible to get to a state where memory safety issues would be deterministically mitigated? Our quest to mitigate memory corruption vulnerabilities led us to examine CHERI Capability Hardware Enhanced RISC Instructions, which provides memory protection features against many exploited...
