CVE-2026-31897 FreeRDP has an out-of-bounds read in `freerdp_bitmap_decompress_planar`

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in freerdpbitmapdecompressplanar when SrcSize is 0. The function dereferences srcp which points to pSrcData without first verifying that SrcSize = 1. When SrcSize is 0 and pSrcData is...
