Descriptions

In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: use cpuhp_state_remove_instance_nocalls() for hisi_hns3_pmu uninit process When tearing down a 'hisi_hns3' PMU, we mistakenly run the CPU hotplug
callbacks after the device has been unregistered, leading to fireworks
when we try to execute empty function callbacks within the driver: | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 | CPU: 0 PID: 15 Comm: cpuhp/0 Tainted: G W O 5.12.0-rc4+ #1 | Hardware name: , BIOS KpxxxFPGA 1P B600 V143 04/22/2021 | pstate: 80400009 (Nzcv daif +PAN -UAO -TCO BTYPE=--) | pc : perf_pmu_migrate_context+0x98/0x38c | lr : perf_pmu_migrate_context+0x94/0x38c | | Call trace: | perf_pmu_migrate_context+0x98/0x38c | hisi_hns3_pmu_offline_cpu+0x104/0x12c [hisi_hns3_pmu] Use cpuhp_state_remove_instance_nocalls() instead of

the PMU device has been unregistered. [will: Rewrote commit message]

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers/perf: hisi: use cpuhp_state_remove_instance_nocalls() para el proceso uninit hisi_hns3_pmu. Al derribar una PMU 'hisi_hns3', ejecutamos por error las devoluciones de llamadas de conexión en caliente de la CPU después de que el dispositivo haya sido anulado del registro, lo que lleva a a fuegos artificiales cuando intentamos ejecutar devoluciones de llamadas de funciones vacías dentro del controlador: | No se puede manejar la desreferencia del puntero NULL del kernel en la dirección virtual 0000000000000000 | CPU: 0 PID: 15 Comunicaciones: cpuhp/0 Contaminado: GWO 5.12.0-rc4+ #1 | Nombre del hardware: , BIOS KpxxxFPGA 1P B600 V143 22/04/2021 | pstate: 80400009 (Nzcv daif +PAN -UAO -TCO BTYPE=--) | ordenador personal: perf_pmu_migrate_context+0x98/0x38c | lr: perf_pmu_migrate_context+0x94/0x38c | | Rastreo de llamadas: | perf_pmu_migrate_context+0x98/0x38c | hisi_hns3_pmu_offline_cpu+0x104/0x12c [hisi_hns3_pmu] Utilice cpuhp_state_remove_instance_nocalls() en lugar de cpuhp_state_remove_instance() para que los notificadores no se ejecuten después de que el dispositivo PMU haya sido anulado del registro.
