{"id":"AZL-51186","summary":"CVE-2024-49916 affecting package kernel 6.6.126.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add NULL check for clk_mgr and clk_mgr-\u003efuncs in dcn401_init_hw\n\nThis commit addresses a potential null pointer dereference issue in the\n`dcn401_init_hw` function. The issue could occur when `dc-\u003eclk_mgr` or\n`dc-\u003eclk_mgr-\u003efuncs` is null.\n\nThe fix adds a check to ensure `dc-\u003eclk_mgr` and `dc-\u003eclk_mgr-\u003efuncs` is\nnot null before accessing its functions. This prevents a potential null\npointer dereference.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:416 dcn401_init_hw() error: we previously assumed 'dc-\u003eclk_mgr' could be null (see line 225)","modified":"2026-04-01T05:16:23.974932Z","published":"2024-10-21T18:15:13Z","upstream":["CVE-2024-49916"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49916"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-51186.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
