SUSE CVE-2025-71203

In the Linux kernel, the following vulnerability has been resolved: riscv: Sanitize syscall table indexing under speculation The syscall number is a user-controlled value used to index into the syscall table. Use arrayindexnospec to clamp this value after the bounds check to prevent speculative...

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...

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...
