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.

The version of capstone installed on the remote host is prior to 3.0.5-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3133 advisory.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0060-1 advisory.

    Security issues fixed:

    - CVE-2025-67873: missing bounds check on user-provided skipdata callback can lead to a heap buffer     overflow       (bsc#1255309).
    - CVE-2025-68114: unchecked `vsnprintf` return value can lead to a stack buffer overflow (bsc#1255310).

    Other updates and bugfixes:

    - Enable static library, and add `libcapstone-devel-static` subpackage.
