// 原语: OOB 读 · 系统进程 · tier 2
// Primitive: OOB read · system process · tier 2
//
// [zh] MVHEVC 层 ID 越界
// 多层 HEVC 的 layer id 在 27.0 未做范围校验，越界值直接进入插件的层表索引。27.2 补入层 ID 校验。
//
// [en] MVHEVC layer id out of range
// Multilayer HEVC layer ids are not range-checked on 27.0, so an out-of-range value goes straight
// into the plugin's layer table index. iOS 27.2 adds layer id validation.
// ── 判别 / oracle ──
// 层 ID 取 0x3F（有效范围之外）。
