{"id":"AZL-51258","summary":"CVE-2024-49914 affecting package kernel for versions less than 6.6.64.2-9","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add null check for pipe_ctx-\u003eplane_state in dcn20_program_pipe\n\nThis commit addresses a null pointer dereference issue in the\n`dcn20_program_pipe` function. The issue could occur when\n`pipe_ctx-\u003eplane_state` is null.\n\nThe fix adds a check to ensure `pipe_ctx-\u003eplane_state` is not null\nbefore accessing. This prevents a null pointer dereference.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 dcn20_program_pipe() error: we previously assumed 'pipe_ctx-\u003eplane_state' could be null (see line 1877)","modified":"2026-04-01T05:17:42.309657Z","published":"2024-10-21T18:15:13Z","upstream":["CVE-2024-49914"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49914"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-51258.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"}]}
