Security researchers at the CISPA Helmholtz Center for Information Security have discovered a vulnerability they’ve called ‘GhostWrite’ that’s caused by a hardware bug in T-Head’s XuanTie C910 and C920 RISC-V CPUs. Vector extensions that are supposed to provide translation of virtual memory addresses to physical addresses don’t work, meaning that an attacker can gain access to the contents of memory and any attached devices.
