CVE-2026-35199

SymCrypt is the core cryptographic function library currently used by Windows. From 103.5.0 to before 103.11.0, The SymCryptXmssSign function passes a 64-bit leaf count value to a helper function that accepts a 32-bit parameter. For XMSS^MT parameter sets with total tree height = 32 which include...

CVE-2026-35199

Summary: CVE-2026-35199 affects the SymCrypt XMSS^MT signing path in Windows. A 64-bit leaf-count is passed to a 32-bit parameter helper, causing silent truncation to zero for XMSS^MT parameter sets with total tree height ≥ 32. This leads to an undersized scratch buffer and a heap buffer overflow...
