CVE-2025-67873 (opens in a new tab)Amendment
The AlmaLinux security team deemed this advisory irrelevant for AlmaLinux:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream capstone package and not the capstone package as distributed by AlmaLinux.
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.
