CVE-2025-71203

CVE-2025-71203 concerns the Linux kernel where a user-controlled syscall number could be used to index the syscall table, enabling potential data leakage via cache side channels. The mitigation is to clamp the index with array_index_nospec() after the bounds check to prevent speculative out-of-bo...

The vulnerability of the arch_kimage_file_post_load_cleanup() function in the arch/riscv/kernel/elf_kexec.c module of the kernel subsystem of the Linux operating system’s RISCV-architecture-based platform allows a attacker to trigger a service failure.

The vulnerability of the archkimagefilepostloadcleanup function in the arch/riscv/kernel/elfkexec.c module of the kernel subsystem of the Linux operating system’s RISCV architecture is related to improper memory release memory leak. Exploiting this vulnerability could allow a remote attacker to...

Sleep Reveals the Nonce: Breaking ECDSA Using Sleep-Based Power Side-Channel Vulnerability

Security of Elliptic Curve Digital Signature Algorithm ECDSA depends on the secrecy of the per-signature nonce. Even partial nonce leakage can expose the long-term private key through lattice-based cryptanalysis. In this paper, we introduce a previously unexplored power side-channel vulnerability...

SimFuzz: Similarity-Guided Block-Level Mutation for RISC-V Processor Fuzzing

The Instruction Set Architecture ISA defines processor operations and serves as the interface between hardware and software. As an open ISA, RISC-V lowers the barriers to processor design and encourages widespread adoption, but also exposes processors to security risks such as functional bugs...
