{"id":"UBUNTU-CVE-2026-119601","details":"AFFLIB through 3.7.22 contains a heap out-of-bounds write vulnerability in af_get_page() that allows attackers to corrupt heap memory by supplying crafted AFF images with mismatched page and sector sizes. Attackers can set a page size larger than and not a multiple of the sector size, causing the sector zero-fill loop to write past the buffer and crash forensic tools.","modified":"2026-11-04T03:30:35.166152777Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-119601"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119601"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119601"},{"type":"REPORT","url":"https://github.com/sshock/AFFLIBv3/issues/61"},{"type":"REPORT","url":"https://github.com/sshock/AFFLIBv3"},{"type":"REPORT","url":"https://github.com/sshock/AFFLIBv3/blob/v3.7.22/lib/afflib_pages.cpp#L309-L315"},{"type":"REPORT","url":"https://hackmd.io/@haindpwn/afflib-aff-get-page-sector-fill-oob-write"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/afflib-through-3.7.22-heap-out-of-bounds-write-in-af-get-page"}],"affected":[{"package":{"name":"afflib","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.6-5ubuntu1","3.7.7-1ubuntu1","3.7.7-3","3.7.7-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"afflib-tools","binary_version":"3.7.7-3ubuntu0.1~esm1"},{"binary_name":"libafflib0v5","binary_version":"3.7.7-3ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}},{"package":{"name":"afflib","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.16-2","3.7.16-2build1","3.7.16-2build2","3.7.16-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"afflib-tools","binary_version":"3.7.16-2ubuntu0.1~esm1"},{"binary_version":"3.7.16-2ubuntu0.1~esm1","binary_name":"libafflib0v5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}},{"package":{"name":"afflib","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.18-3"],"ecosystem_specific":{"binaries":[{"binary_name":"afflib-tools","binary_version":"3.7.18-3"},{"binary_name":"libafflib0v5","binary_version":"3.7.18-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}},{"package":{"name":"afflib","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.19-1","3.7.19-2","3.7.19-2build1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.7.19-2build1","binary_name":"afflib-tools"},{"binary_version":"3.7.19-2build1","binary_name":"libafflib0v5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}},{"package":{"name":"afflib","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.20-1","3.7.20-1.1ubuntu3","3.7.20-1.1ubuntu4","3.7.20-1.1ubuntu5"],"ecosystem_specific":{"binaries":[{"binary_name":"afflib-tools","binary_version":"3.7.20-1.1ubuntu5"},{"binary_name":"libafflib0t64","binary_version":"3.7.20-1.1ubuntu5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}},{"package":{"name":"afflib","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.22-1build1","3.7.22-2","3.7.22-2build1","3.7.22-3"],"ecosystem_specific":{"binaries":[{"binary_name":"afflib-tools","binary_version":"3.7.22-3"},{"binary_name":"libafflib0t64","binary_version":"3.7.22-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}},{"package":{"name":"afflib","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/afflib?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.22-1","3.7.22-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"afflib-tools","binary_version":"3.7.22-1build1"},{"binary_name":"libafflib0t64","binary_version":"3.7.22-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119601.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
