[PATCH v3 0/1] MR9347: windowscodecs: Fix off-by-one check in IcoDecoder_GetFrame.

[zhengyong chen (＠chenzhengyong)]

The frame index should be strictly less than idCount. Previously, an index equal to idCount was not rejected, leading to an out-of-range access.

Although this bug was not fatal because subsequent IStream_Read and related functions also perform boundary checks, it is better to catch the invalid index early for clarity and consistency.
