{"id":"UBUNTU-CVE-2026-7111","details":"Text::CSV_XS versions before 1.62 for Perl have a use-after-free when registered callbacks extend the Perl argument stack, which may enable type confusion or memory corruption. The Parse, print, getline, and getline_all methods invoke registered callbacks (for example after_parse, before_print, or on_error) and cache the Perl argument stack pointer across the call. If a callback extends the argument stack enough to trigger a reallocation, the return value is written through the stale pointer into the freed buffer, and the caller reads the original $self argument as the return value instead. Calling code that expects parsed data from getline_all receives the Text::CSV_XS object in its place, leading to logic errors or crashes. Text::CSV_XS objects used without any registered callbacks are not affected.","modified":"2026-05-26T19:29:39.582859264Z","published":"2026-04-29T15:16:00Z","upstream":["CVE-2026-7111"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-7111"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-7111"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/39453344/"}],"affected":[{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.19-1","1.20-1","1.20-1build1","1.21-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.21-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.26-1build1","1.34-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.34-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.39-1","1.39-1build1","1.40-1","1.41-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.41-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.45-1","1.46-1","1.47-1","1.47-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.47-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.51-1","1.52-1","1.53-1","1.53-1build1","1.53-1build2","1.53-1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.53-1build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.60-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libtext-csv-xs-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60-1","1.61-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtext-csv-xs-perl","binary_version":"1.61-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7111.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
