CVE-2026-23067

CVE-2026-23067 centers on an integer signedness bug in the Linux kernel’s ARM IOMMU path (io-pgtable-arm). __arm_lpae_unmap() returned a size_t (unsigned) but could yield -ENOENT on error, turning into a large positive value on 64-bit systems and propagating through the call chain to __iommu_unma...

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...
