CVE-2021-47414

Summary: CVE-2021-47414 concerns a Linux kernel vulnerability on RISCV (SiFive HiFive Unmatched) where ftrace patching may trigger an illegal instruction due to icache/dcache synchronization across CPUs. The root cause is that icache of the current CPU is not flushed before other CPUs are asked t...
