The array is initialized with four elements, corresponding\nto the four calls to stream_enc_regs() in the array initializer. This\nmeans that valid indices for this array are 0, 1, 2, and 3.\n\nThe error message 'stream_enc_regs' 4 <= 5 below, is indicating that\nthere is an attempt to access this array with an index of 5, which is\nout of bounds. This could lead to undefined behavior\n\nHere, eng_id is used as an index to access the stream_enc_regs array. If\neng_id is 5, this would result in an out-of-bounds access on the\nstream_enc_regs array.\n\nThus fixing Buffer overflow error in dcn401_stream_encoder_create\n\nFound by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn401/dcn401_resource.c:1209 dcn401_stream_encoder_create() error: buffer overflow 'stream_enc_regs' 4 <= 5","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-129"],"references":["https://git.kernel.org/stable/c/00872dcc2a3e4a42155c2f3b7f21952a62301035","https://git.kernel.org/stable/c/b219b46ad42df1dea9258788bcfea37181f3ccb2","https://git.kernel.org/stable/c/bdf606810210e8e07a0cdf1af3c467291363b295"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2024-49970","score":0.00295,"percentile":0.21917,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
