Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/pm: fix a double-free in si_dpm_init

When the allocation of
adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails,
amdgpu_free_extended_power_table is called to free some fields of adev.
However, when the control flow returns to si_dpm_sw_init, it goes to
label dpm_failed and calls si_dpm_fini, which calls
amdgpu_free_extended_power_table again and free those fields again. Thus
a double-free is triggered.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/pm: corrige una double free en si_dpm_init Cuando fallo la asignación de adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries, se llama a amdgpu_free_extended_power_table para liberar algunos campos de adev. Sin embargo, cuando el flujo de control regresa a si_dpm_sw_init, va a la etiqueta dpm_failed y llama a si_dpm_fini, que llama a amdgpu_free_extended_power_table nuevamente y libera esos campos nuevamente. De este modo se activa un double free.
