CVE-2026-1140466.5 MED—
——0FreeRDP 3.0.0 before 3.32.0 contains a null-pointer dereference in the smartcard emulation backend that accepts a null per-reader name in SCardGetStatusChange requests. A malicious RDP server can send a crafted reader-state entry with a null szReader, causing strcmp or _wcscmp to crash the client process.9hCVE-2026-1136805.5 MED—
——0HarfBuzz from 8.0.0 through 14.6.0 contains a NULL pointer dereference vulnerability in the experimental WebAssembly shaper host imports buffer_set_contents, face_create, and font_set_coords. Attackers can supply a crafted font whose embedded wasm module passes out-of-range addresses with non-zero lengths, crashing any application that shapes text with the font.14hCVE-2026-43842—18.6%

——6Pillow is a Python imaging library. From 12.0.0 until 13.0.0, Pillow's Image.merge() can dereference a null image8 plane. Validation skips the first input band, allowing a 32-bit integer or floating-point image backed by image32 storage to be merged as a narrower multiband image. A crafted IPTC file can reach this path when an application opens and loads it, or a caller can invoke Image.merge() directly with such a first band. This causes a native process crash. This issue is fixed in version 13.0.0.15h
