In the Linux kernel, the following vulnerability has been resolved: AppArmor: The recursive approach used for removing profiles has been replaced with an iterative one. The profile removal code uses recursion when removing nested profiles, which can lead to exhaustion of the kernel’s stack and...

RejSCore: Rejection Sampling Core for Multivariate-Based Public Key Cryptography

Post-quantum multivariate public key cryptography MPKC schemes resist quantum threats but require heavy operations, such as rejection sampling, which challenge resource-limited devices. Prior hardware designs have addressed various aspects of MPKC signature generation. However, rejection sampling...
