{"id":"UBUNTU-CVE-2026-111166","details":"libmikmod through 3.3.15 contains a heap out-of-bounds read vulnerability in the IMF_Load() loader that allows attackers to read beyond allocated memory by supplying a crafted IMF module. Attackers can enable the linear-period header flag and map notes to out-of-range samples, causing noteindex indexing far past the heap allocation and crashing applications that load the file.","modified":"2026-10-17T12:58:04.117532730Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111166"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111166"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111166"},{"type":"REPORT","url":"https://github.com/sezero/mikmod"},{"type":"REPORT","url":"https://github.com/sezero/mikmod/blob/6e658155f7e6b394a288dac796ba572634553fad/libmikmod/loaders/load_imf.c#L702-L712"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/libmikmod-mtm-imf-loader-oob-read"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/libmikmod-through-3.3.15-heap-out-of-bounds-read-via-imf-load"}],"affected":[{"package":{"name":"libmikmod","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.7-1","3.3.8-1","3.3.8-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libmikmod-config","binary_version":"3.3.8-2"},{"binary_name":"libmikmod3","binary_version":"3.3.8-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}},{"package":{"name":"libmikmod","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.11.1-1","3.3.11.1-3"],"ecosystem_specific":{"binaries":[{"binary_version":"3.3.11.1-3","binary_name":"libmikmod-config"},{"binary_name":"libmikmod3","binary_version":"3.3.11.1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}},{"package":{"name":"libmikmod","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.11.1-4"],"ecosystem_specific":{"binaries":[{"binary_name":"libmikmod-config","binary_version":"3.3.11.1-4"},{"binary_version":"3.3.11.1-4","binary_name":"libmikmod3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}},{"package":{"name":"libmikmod","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.11.1-6"],"ecosystem_specific":{"binaries":[{"binary_version":"3.3.11.1-6","binary_name":"libmikmod-config"},{"binary_name":"libmikmod3","binary_version":"3.3.11.1-6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}},{"package":{"name":"libmikmod","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.11.1-7","3.3.11.1-7build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmikmod-config","binary_version":"3.3.11.1-7build1"},{"binary_name":"libmikmod3","binary_version":"3.3.11.1-7build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}},{"package":{"name":"libmikmod","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.13-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.3.13-1build1","binary_name":"libmikmod3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}},{"package":{"name":"libmikmod","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libmikmod?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.13-1","3.3.13-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.3.13-1build1","binary_name":"libmikmod3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111166.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
