{"id":"UBUNTU-CVE-2026-41445","details":"KissFFT before commit 8a8e66e contains an integer overflow vulnerability in the kiss_fftndr_alloc() function in kiss_fftndr.c where the allocation size calculation dimOther*(dimReal+2)*sizeof(kiss_fft_scalar) overflows signed 32-bit integer arithmetic before being widened to size_t, causing malloc() to allocate an undersized buffer. Attackers can trigger heap buffer overflow by providing crafted dimensions that cause the multiplication to exceed INT_MAX, allowing writes beyond the allocated buffer region when kiss_fftndr() processes the data.","modified":"2026-09-10T21:30:17.522615638Z","published":"2026-04-20T17:16:00Z","related":["USN-8745-1"],"upstream":["CVE-2026-41445"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-41445"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-41445"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8745-1"}],"affected":[{"package":{"name":"kissfft","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/kissfft?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"131.1.0-2ubuntu0.1~esm1"}]}],"versions":["131.1.0-1","131.1.0-2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"kissfft-tools","binary_version":"131.1.0-2ubuntu0.1~esm1"},{"binary_name":"libkissfft-float131","binary_version":"131.1.0-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41445.json"}},{"package":{"name":"kissfft","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/kissfft?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"131.1.0-3ubuntu0.1~esm1"}]}],"versions":["131.1.0-3","131.1.0-3build1","131.1.0-3build2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"kissfft-tools","binary_version":"131.1.0-3ubuntu0.1~esm1"},{"binary_name":"libkissfft-float131","binary_version":"131.1.0-3ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41445.json"}},{"package":{"name":"kissfft","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/kissfft?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["131.1.0-3build2"],"ecosystem_specific":{"binaries":[{"binary_name":"kissfft-tools","binary_version":"131.1.0-3build2"},{"binary_name":"libkissfft-float131","binary_version":"131.1.0-3build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41445.json"}},{"package":{"name":"kissfft","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/kissfft?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"131.1.0-4ubuntu0.1~esm1"}]}],"versions":["131.1.0-3build2","131.1.0-4"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"131.1.0-4ubuntu0.1~esm1","binary_name":"kissfft-tools"},{"binary_name":"libkissfft-float131","binary_version":"131.1.0-4ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41445.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
