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.

조치방안
제3자 참조와 수정 버전 값(4.19.306, 5.4.268, 5.10.209, 5.15.148, 6.1.75, 6.6.14, 6.7.2)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, linux kernel, debian linux 4.19.306, 5.4.268, 5.10.209, 5.15.148, 6.1.75, 6.6.14, 6.7.2 기준을 충족하는지 확인합니다. 이어서 유형 미확정 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
