Systematic Assessment of Cache Timing Vulnerabilities on RISC-V Processors

While interest in the open RISC-V instruction set architecture is growing, tools to assess the security of concrete processor implementations are lacking. There are dedicated tools and benchmarks for common microarchitectural side-channel vulnerabilities for popular processor families such as Int...

CVE-2024-44067

The T-Head XuanTie C910 CPU in the TH1520 SoC and the T-Head XuanTie C920 CPU in the SOPHON SG2042 have instructions that allow unprivileged attackers to write to arbitrary physical memory locations, aka GhostWrite...
