CVE-2023-53583

CVE-2023-53583 concerns the Linux kernel RISC‑V PMU driver. The issue arises from the perf subsystem: after perf_event_overflow(), the RISC‑V PMU driver did not update PERF_HES_STOPPED, and the unthrottle path could trigger riscv_pmu_start(), emitting a WARN_ON_ONCE. The fixed change removes the ...
