Astra Linux – Vulnerability in gnupg1

Libgcrypt before version 1.7.8 is vulnerable to a cache-side-channel attack that can lead to a complete failure of the RSA-1024 algorithm. This attack occurs when the left-to-right method is used for computing the sliding-window expansion. It is believed that the same attack also works on the...

HermiCache: Enclave-Aware Cache Replacement for Trusted Execution Environments

Trusted Execution Environments TEEs protect enclave memory from untrusted software but remain vulnerable to cache-based side-channel attacks due to shared microarchitectural resources. Existing countermeasures use techniques such as cache partitioning or randomization: these solutions are not ide...

ROS-20260819-73-0075

The vulnerability in Python-Django relates to the exposure of information through caching. Exploiting this vulnerability allows an attacker to gain access to the memory of a supervisor machine or other virtual machines. This can be achieved by implementing attacks through secondary channels,...

SLAC: Access-Driven CPU-To-GPU Side-Channel Attacks Via System-Level Cache on Apple Silicon

Modern heterogeneous System-on-Chip designs integrate CPU cores and a GPU that share a last-level cache LLC or system-level cache SLC. This sharing exposes a new cross-domain attack surface, and existing attacks on integrated platforms either exploit coarse-grained cache-occupancy contention or...
