{"id":"CVE-2024-49915","summary":"drm/amd/display: Add NULL check for clk_mgr in dcn32_init_hw","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add NULL check for clk_mgr in dcn32_init_hw\n\nThis commit addresses a potential null pointer dereference issue in the\n`dcn32_init_hw` function. The issue could occur when `dc-\u003eclk_mgr` is\nnull.\n\nThe fix adds a check to ensure `dc-\u003eclk_mgr` is not null before\naccessing its functions. This prevents a potential null pointer\ndereference.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn32/dcn32_hwseq.c:961 dcn32_init_hw() error: we previously assumed 'dc-\u003eclk_mgr' could be null (see line 782)","modified":"2026-04-02T12:21:06.375617Z","published":"2024-10-21T18:01:42.866Z","related":["SUSE-SU-2025:0117-1","SUSE-SU-2025:0153-1","SUSE-SU-2025:0154-1","SUSE-SU-2025:0289-1","SUSE-SU-2025:20165-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20248-1","SUSE-SU-2025:20249-1","USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49915.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0d94d9cbd9fec7344d230c4f7b781826f7799c60"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d1854c86d02cea8f8a0c0ca05f4ab14292baf3d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c395fd47d1565bd67671f45cca281b3acc2c31ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ec1be3c527b4a5fc85bcc1b0be7cec08bf60c796"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f0454b3cb0584a6bf275aeb49be61a760fd546a2"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49915.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49915"},{"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":"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c"},{"fixed":"0d94d9cbd9fec7344d230c4f7b781826f7799c60"},{"fixed":"ec1be3c527b4a5fc85bcc1b0be7cec08bf60c796"},{"fixed":"f0454b3cb0584a6bf275aeb49be61a760fd546a2"},{"fixed":"7d1854c86d02cea8f8a0c0ca05f4ab14292baf3d"},{"fixed":"c395fd47d1565bd67671f45cca281b3acc2c31ef"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-49915.json"}}],"schema_version":"1.7.5"}
