CVE-2023-52859

CVE-2023-52859 affects the Linux kernel perf: hisi uncore PMU registration. A use-after-free can occur when the PMU register path fails and the uncore PMU offline callback is invoked, potentially migrating the PMU context. The fix replaces cpuhp_state_remove_instance() with cpuhp_state_remove_ins...
