{"id":"UBUNTU-CVE-2026-109970","details":"A flaw was found in the clevis PKCS#11 pin. The clevis-luks-pkcs11-askpin script writes the PKCS#11 token PIN in plaintext to a file without setting restrictive permissions. Under the default process umask, the file is world-readable. Additionally, the PIN file is not reliably cleaned up if the decryption script exits early, leaving the PIN accessible indefinitely.","modified":"2026-10-17T12:59:51.306693976Z","published":"2026-10-15T00:00:00Z","upstream":["CVE-2026-109970"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-109970"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-109970"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-109970"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2550362"}],"affected":[{"package":{"name":"clevis","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/clevis?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8-1","8-1ubuntu0.1","8-1ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_version":"8-1ubuntu0.2","binary_name":"clevis"},{"binary_version":"8-1ubuntu0.2","binary_name":"clevis-dracut"},{"binary_name":"clevis-initramfs","binary_version":"8-1ubuntu0.2"},{"binary_name":"clevis-luks","binary_version":"8-1ubuntu0.2"},{"binary_version":"8-1ubuntu0.2","binary_name":"clevis-systemd"},{"binary_name":"clevis-udisks2","binary_version":"8-1ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-109970.json"}},{"package":{"name":"clevis","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/clevis?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11-2","12-1ubuntu1","12-1ubuntu2","12-1ubuntu2.1","12-1ubuntu2.2","12-1ubuntu2.3"],"ecosystem_specific":{"binaries":[{"binary_name":"clevis","binary_version":"12-1ubuntu2.3"},{"binary_name":"clevis-dracut","binary_version":"12-1ubuntu2.3"},{"binary_name":"clevis-initramfs","binary_version":"12-1ubuntu2.3"},{"binary_name":"clevis-luks","binary_version":"12-1ubuntu2.3"},{"binary_version":"12-1ubuntu2.3","binary_name":"clevis-systemd"},{"binary_name":"clevis-tpm2","binary_version":"12-1ubuntu2.3"},{"binary_name":"clevis-udisks2","binary_version":"12-1ubuntu2.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-109970.json"}},{"package":{"name":"clevis","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/clevis?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["16-2","18-1","18-1ubuntu1","18-1ubuntu1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"clevis","binary_version":"18-1ubuntu1.1"},{"binary_version":"18-1ubuntu1.1","binary_name":"clevis-dracut"},{"binary_version":"18-1ubuntu1.1","binary_name":"clevis-initramfs"},{"binary_name":"clevis-luks","binary_version":"18-1ubuntu1.1"},{"binary_name":"clevis-systemd","binary_version":"18-1ubuntu1.1"},{"binary_version":"18-1ubuntu1.1","binary_name":"clevis-tpm2"},{"binary_name":"clevis-udisks2","binary_version":"18-1ubuntu1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-109970.json"}},{"package":{"name":"clevis","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/clevis?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["19-3","19-6","19-6build1","19-6build2","20-1","20-1ubuntu0.24.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"20-1ubuntu0.24.04.1","binary_name":"clevis"},{"binary_name":"clevis-dracut","binary_version":"20-1ubuntu0.24.04.1"},{"binary_version":"20-1ubuntu0.24.04.1","binary_name":"clevis-initramfs"},{"binary_name":"clevis-luks","binary_version":"20-1ubuntu0.24.04.1"},{"binary_version":"20-1ubuntu0.24.04.1","binary_name":"clevis-systemd"},{"binary_version":"20-1ubuntu0.24.04.1","binary_name":"clevis-tpm2"},{"binary_name":"clevis-udisks2","binary_version":"20-1ubuntu0.24.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-109970.json"}},{"package":{"name":"clevis","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/clevis?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20-1ubuntu2","23-1","23-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"clevis","binary_version":"23-1build1"},{"binary_name":"clevis-dracut","binary_version":"23-1build1"},{"binary_name":"clevis-initramfs","binary_version":"23-1build1"},{"binary_name":"clevis-luks","binary_version":"23-1build1"},{"binary_version":"23-1build1","binary_name":"clevis-systemd"},{"binary_name":"clevis-tpm2","binary_version":"23-1build1"},{"binary_version":"23-1build1","binary_name":"clevis-udisks2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-109970.json"}},{"package":{"name":"clevis","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/clevis?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20-1","20-1build1","20-1ubuntu1","20-1ubuntu2"],"ecosystem_spe
