CVE-2023-52860

CVE-2023-52860 relates to the Linux kernel; the root issue occurs in the perf driver when tearing down a hisi_hns3 PMU, where CPU hotplug callbacks could run after the PMU is unregistered, leading to a NULL pointer dereference. The fix uses cpuhp_state_remove_instance_nocalls() instead of cpuhp_s...

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...

CVE-2023-52675

Concretely tied to CVE-2023-52675 in the Linux kernel: the issue is twofold. (1) powerpc/imc-pmu: update_events_in_group() gained a null pointer check to prevent dereferencing NULL during event updates. (2) kasprintf() can return NULL if memory allocation fails, which could lead to a NULL pointer...
