发布于3月6日3月6日 Members Debian: CVE-2023-52691: linux -- security update Severity 7 CVSS (AV:L/AC:L/Au:S/C:C/I:C/A:C) Published 05/17/2024 Created 06/28/2024 Added 06/27/2024 Modified 01/28/2025 Description 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. Solution(s) debian-upgrade-linux References https://attackerkb.com/topics/cve-2023-52691 CVE - 2023-52691 DLA-3840-1 DLA-3841-1
