The issue could occur when\n`pipe_ctx->plane_state` is null.\n\nThe fix adds a check to ensure `pipe_ctx->plane_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->plane_state' could be null (see line 1877)","state":0,"publishedAt":"2024-10-21T18:01:42.215+00:00","modifiedAt":"2026-10-30T12:19:35.058+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c\",\n                            \"lessThan\": \"21c613e1c6ae45bb29ebc156d22060f034cc5665\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c\",\n                            \"lessThan\": \"68f75e6f08aad66069a629db8d7840919156c761\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c\",\n                            \"lessThan\": \"65a6fee22d5cfa645cb05489892dc9cd3d142fc2\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c\",\n                            \"lessThan\": \"8e4ed3cf1642df0c4456443d865cff61a9598aa8\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"4.15\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"4.15\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.1.191\",\n                            \"lessThanOrEqual\": \"6.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.6.64\",\n                            \"lessThanOrEqual\": \"6.6.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.11.3\",\n                            \"lessThanOrEqual\": \"6.11.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/21c613e1c6ae45bb29ebc156d22060f034cc5665","https://git.kernel.org/stable/c/68f75e6f08aad66069a629db8d7840919156c761","https://git.kernel.org/stable/c/65a6fee22d5cfa645cb05489892dc9cd3d142fc2","https://git.kernel.org/stable/c/8e4ed3cf1642df0c4456443d865cff61a9598aa8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-49914","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-49914","identifiers":["CVE-2024-49914"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
