CVE-2026-111270: libmodplug through 0.8.9.1 Heap Out-of-Bounds Write via CSoundFile::ReadDSM

MediumCVSS 6.9 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: libmodplug (openSUSE:Leap 16.0) 0.8.9.0+git20170610.f6dd59a-bp160.2.1; libmodplug (openSUSE:Tumbleweed) 0.8.9.0+git20170610.f6dd59a-4.1.

Low priority for now. Upgrade to libmodplug (openSUSE:Leap 16.0) 0.8.9.0+git20170610.f6dd59a-bp160.2.1; libmodplug (openSUSE:Tumbleweed) 0.8.9.0+git20170610.f6dd59a-4.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

libmodplug through 0.8.9.1 contains a heap-based out-of-bounds write in CSoundFile::ReadDSM() in src/load_dsm.cpp because nPat is never checked against MAX_PATTERNS. Attackers can supply a crafted DSM file with over 240 PATT chunks or a wrapping patt_len value to corrupt heap memory and crash the consuming process.
