{"id":"DEBIAN-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":"2026-09-14T17:03:33.690496900Z","published":"2026-04-20T17:16:37.160Z","upstream":["CVE-2026-41445"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41445"}],"affected":[{"package":{"name":"kissfft","ecosystem":"Debian:12","purl":"pkg:deb/debian/kissfft?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"131.1.0-4.1~deb12u1"}]}],"versions":["131.1.0-3","131.1.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41445.json"}},{"package":{"name":"kissfft","ecosystem":"Debian:13","purl":"pkg:deb/debian/kissfft?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"131.1.0-4.1~deb13u1"}]}],"versions":["131.1.0-3","131.1.0-4","131.1.0-4.1~deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41445.json"}},{"package":{"name":"kissfft","ecosystem":"Debian:14","purl":"pkg:deb/debian/kissfft?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"131.1.0-4.1"}]}],"versions":["131.1.0-3","131.1.0-4","131.1.0-4.1~deb12u1","131.1.0-4.1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41445.json"}}],"schema_version":"1.9.0","severity":[{"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
