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.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0098 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-68114:
    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 SStreams 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:
    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 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.
