El problema podr\u00eda ocurrir cuando el \u00edndice 'i' excede la cantidad de puntos de funci\u00f3n de transferencia (TRANSFER_FUNC_POINTS). La correcci\u00f3n agrega una verificaci\u00f3n para garantizar que 'i' est\u00e9 dentro de los l\u00edmites antes de acceder a los puntos de funci\u00f3n de transferencia. Si 'i' est\u00e1 fuera de los l\u00edmites, la funci\u00f3n devuelve falso para indicar un error. cm3_helper_translate_curve_to_hw_format() error: desbordamiento de b\u00fafer 'output_tf-&gt;tf_pts.red' 1025 &lt;= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:181 cm3_helper_translate_curve_to_hw_format() error: desbordamiento de b\u00fafer 'output_tf-&gt;tf_pts.green' 1025 &lt;= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:182 Error de cm3_helper_translate_curve_to_hw_format(): desbordamiento de b\u00fafer 'output_tf-&gt;tf_pts.blue' 1025 &lt;= s32max"}], "id": "CVE-2024-49969", "lastModified": "2025-11-03T23:16:35.590", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 7.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 5.9, "source": "nvd@nist.gov", "type": "Primary"}]}, "published": "2024-10-21T18:15:17.910", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/0f1e222a4b41d77c442901d166fbdca967af0d86"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/578422ddae3d13362b64e77ef9bab98780641631"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/7ab69af56a23859b647dee69fa1052c689343621"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/929506d5671419cffd8d01e9a7f5eae53682a838"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/b9d8b94ec7e67f0cae228c054f77b73967c389a3"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/c13f9c62015c56a938304cef6d507227ea3e0039"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/d81873f9e715b72d4f8d391c8eb243946f784dfc"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-129"}], "source": "nvd@nist.gov", "type": "Primary"}]}
