CVE-2024-26796

The CVE-2024-26796 vulnerability affects the Linux kernel perf subsystem on RISCV with the PMU legacy path. The root cause is that the ctr_get_width function was not defined for the legacy configuration (CONFIG_RISCV_PMU_LEGACY=y, CONFIG_RISCV_PMU_SBI=n), causing a NULL pointer dereference in per...
