However, the offset\nparameter passed to dp_get_eq_aux_rd_interval() can be as large as\nMAX_REPEATER_CNT (8) when a sink reports 8 LTTPR repeaters via DPCD.\nThis leads to an out-of-bounds read of aux_rd_interval[7] when offset\nis 8.\n\nFix this by growing aux_rd_interval to MAX_REPEATER_CNT elements to\naccommodate the full range of valid repeater counts defined by the DP\nspec.\n\n(cherry picked from commit a55a458a8df37a65ffda5cf721d554a8f74f6b04)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/454d3b3d499c18373f8960d31aea48338a3ca9e0","https://git.kernel.org/stable/c/7c5f2d16a8f4464bf2a719ceb2316b8a6b87a3c0","https://git.kernel.org/stable/c/a632474c793b7f2a9bbd3d8e3d0dd7d256989300","https://git.kernel.org/stable/c/dc1490927d79fe9621e29f4a4f5d7b5ccb6aea3e","https://git.kernel.org/stable/c/e8b4d37eba05141ee01794fc6b7f2da808cee83b"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-53330","score":0.00132,"percentile":0.02751,"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).
