{"id":"CVE-2023-52691","summary":"drm/amd/pm: fix a double-free in si_dpm_init","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/pm: fix a double-free in si_dpm_init\n\nWhen the allocation of\nadev-\u003epm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails,\namdgpu_free_extended_power_table is called to free some fields of adev.\nHowever, when the control flow returns to si_dpm_sw_init, it goes to\nlabel dpm_failed and calls si_dpm_fini, which calls\namdgpu_free_extended_power_table again and free those fields again. Thus\na double-free is triggered.","modified":"2026-04-02T09:43:14.450458Z","published":"2024-05-17T14:24:51.294Z","related":["SUSE-SU-2024:1979-1","SUSE-SU-2024:1983-1","SUSE-SU-2024:2008-1","SUSE-SU-2024:2019-1","SUSE-SU-2024:2135-1","SUSE-SU-2024:2184-1","SUSE-SU-2024:2190-1","SUSE-SU-2024:2203-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20249-1","USN-6818-2","USN-6819-2"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52691.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/06d95c99d5a4f5accdb79464076efe62e668c706"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2bf47c89bbaca2bae16581ef1b28aaec0ade0334"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac16667237a82e2597e329eb9bc520d1cf9dff30"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aeed2b4e4a70c7568d4a5eecd6a109713c0dfbf4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/afe9f5b871f86d58ecdc45b217b662227d7890d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca8e2e251c65e5a712f6025e27bd9b26d16e6f4a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f957a1be647f7fc65926cbf572992ec2747a93f2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb1936cb587262cd539e84b34541abb06e42b2f9"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52691.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52691"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"841686df9f7d2942cfd94d024b8591fa3f74ef7c"},{"fixed":"afe9f5b871f86d58ecdc45b217b662227d7890d0"},{"fixed":"06d95c99d5a4f5accdb79464076efe62e668c706"},{"fixed":"aeed2b4e4a70c7568d4a5eecd6a109713c0dfbf4"},{"fixed":"2bf47c89bbaca2bae16581ef1b28aaec0ade0334"},{"fixed":"f957a1be647f7fc65926cbf572992ec2747a93f2"},{"fixed":"fb1936cb587262cd539e84b34541abb06e42b2f9"},{"fixed":"ca8e2e251c65e5a712f6025e27bd9b26d16e6f4a"},{"fixed":"ac16667237a82e2597e329eb9bc520d1cf9dff30"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-52691.json"}}],"schema_version":"1.7.5"}
