Severity ?
4.8 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L
CWE
  • CWE-124 - Buffer Underwrite ('Buffer Underflow')
  • CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
Summary
Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue.

CVE-2025-67873 (GCVE-0-2025-67873)
Vulnerability from cvelistv5
Published
2025-12-17 21:12
Modified
2025-12-18 15:09
Severity ?
4.8 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L
CWE
  • CWE-122 - Heap-based Buffer Overflow
Summary
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 cs_disasm/cs_disasm_iter memcpy more than 24 bytes into cs_insn.bytes, causing a heap buffer overflow in the disassembly path. Commit cbef767ab33b82166d263895f24084b75b316df3 fixes the issue.
