{"id":"CVE-2024-49894","summary":"drm/amd/display: Fix index out of bounds in degamma hardware format translation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix index out of bounds in degamma hardware format translation\n\nFixes index out of bounds issue in\n`cm_helper_translate_curve_to_degamma_hw_format` function. The issue\ncould occur when the index 'i' exceeds the number of transfer function\npoints (TRANSFER_FUNC_POINTS).\n\nThe fix adds a check to ensure 'i' is within bounds before accessing the\ntransfer function points. If 'i' is out of bounds the function returns\nfalse to indicate an error.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf-\u003etf_pts.red' 1025 \u003c= s32max\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:595 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf-\u003etf_pts.green' 1025 \u003c= s32max\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:596 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf-\u003etf_pts.blue' 1025 \u003c= s32max","modified":"2026-04-02T12:21:05.495636Z","published":"2024-10-21T18:01:28.360Z","related":["MGASA-2024-0344","MGASA-2024-0345","SUSE-SU-2024:3983-1","SUSE-SU-2024:3984-1","SUSE-SU-2024:3985-1","SUSE-SU-2024:4100-1","SUSE-SU-2024:4314-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:0034-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","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-2024-49894.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/07078fa5d589a7fbce8f81ea8acf7aa0021ab38e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/122e3a7a8c7bcbe3aacddd6103f67f9f36bed473"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2495c8e272d84685403506833a664fad932e453a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f5da549535be8ccd2ab7c9abac8562ad370b181"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b3dfa878257a7e98830b3009ca5831a01d8f85fc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7e99058eb2e86aabd7a10761e76cae33d22b49f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c130a3c09e3746c1a09ce26c20d21d449d039b1d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6979719012a90e5b8e3bc31725fbfdd0b9b2b79"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f5f6d90087131812c1e4b9d3103f400f1624396d"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49894.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49894"},{"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":"b3dfa878257a7e98830b3009ca5831a01d8f85fc"},{"fixed":"f5f6d90087131812c1e4b9d3103f400f1624396d"},{"fixed":"c130a3c09e3746c1a09ce26c20d21d449d039b1d"},{"fixed":"c6979719012a90e5b8e3bc31725fbfdd0b9b2b79"},{"fixed":"2495c8e272d84685403506833a664fad932e453a"},{"fixed":"122e3a7a8c7bcbe3aacddd6103f67f9f36bed473"},{"fixed":"2f5da549535be8ccd2ab7c9abac8562ad370b181"},{"fixed":"07078fa5d589a7fbce8f81ea8acf7aa0021ab38e"},{"fixed":"b7e99058eb2e86aabd7a10761e76cae33d22b49f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-49894.json"}}],"schema_version":"1.7.5"}
