CVE-2026-23217

CVE-2026-23217 relates to the Linux kernel on RISC-V where tracing the sbi_ecall functions can cause a deadlock in the snapshot path. The root cause is that sbi_ecall triggers a ringbuffer snapshot which may re-enter __sbi_ecall via an IPI, creating an endless loop when initial __sbi_ecall is pre...
