CVE-2025-68114 Capstone doesn't check vsnprintf return in SStream_concat, allows stack buffer underflow and overflow

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStreamconcat lets a malicious csoptmem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit...

CVE-2025-67873

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, Skipdata length is not bounds-checked, so a user-provided skipdata callback can make csdisasm/csdisasmiter memcpy more than 24 bytes into csinsn.bytes, causing a heap buffer overflow in the disassembly path. Commit...
