-----Original Message----- From: Wang, Yang(Kevin) <[email protected]> Sent: Tuesday, June 23, 2026 9:49 PM To: [email protected] Cc: Deucher, Alexander <[email protected]>; Zhang, Hawking <[email protected]>; Feng, Kenneth <[email protected]>; Kamal, Asad <[email protected]> Subject: [PATCH v2 1/3] drm/amd/pm: Validate Vega10 PPTable subtable bounds v1: Vega10 PPTable parsing uses VBIOS-provided offsets, revision fields and entry counts to locate subtables. Malformed data can otherwise drive out-of-bounds reads from soft_pp_table_size, and voltage lookup tables can overrun their fixed-size destination arrays. Add shared bounds helpers and validate fixed-size subtables, dynamic entry arrays and revision-specific layouts before consuming thermal, fan, power-tune, clock dependency, PCIE, hard-limit and voltage lookup data. v2: if ucRevId is not matched, fallback to default table size instead of returning -EINVAL.
