{"id":"UBUNTU-CVE-2025-55158","details":"Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1406, when processing nested tuples during Vim9 script import operations, an error during evaluation can trigger a double-free in Vim’s internal typed value (typval_T) management. Specifically, the clear_tv() function may attempt to free memory that has already been deallocated, due to improper lifetime handling in the handle_import / ex_import code paths. The vulnerability can only be triggered if a user explicitly opens and executes a specially crafted Vim script. This issue has been patched in version 9.1.1406.","modified":"2025-08-14T16:58:32Z","published":"2025-08-11T23:15:00Z","withdrawn":"2025-08-18T17:08:27Z","upstream":["CVE-2025-55158"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-55158"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-55158"},{"type":"REPORT","url":"https://github.com/vim/vim/commit/9772025d24e939fd84b85748ce35c26874c05775"},{"type":"REPORT","url":"https://github.com/vim/vim/releases/tag/v9.1.1406"},{"type":"REPORT","url":"https://github.com/vim/vim/security/advisories/GHSA-5fg8-wvx3-583x"}],"affected":[{"package":{"name":"vim","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/vim@2:7.4.052-1ubuntu3.1+esm21?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:7.4.000-1ubuntu2","2:7.4.052-1ubuntu1","2:7.4.052-1ubuntu2","2:7.4.052-1ubuntu3","2:7.4.052-1ubuntu3.1","2:7.4.052-1ubuntu3.1+esm1","2:7.4.052-1ubuntu3.1+esm3","2:7.4.052-1ubuntu3.1+esm4","2:7.4.052-1ubuntu3.1+esm5","2:7.4.052-1ubuntu3.1+esm6","2:7.4.052-1ubuntu3.1+esm7","2:7.4.052-1ubuntu3.1+esm8","2:7.4.052-1ubuntu3.1+esm9","2:7.4.052-1ubuntu3.1+esm10","2:7.4.052-1ubuntu3.1+esm11","2:7.4.052-1ubuntu3.1+esm12","2:7.4.052-1ubuntu3.1+esm13","2:7.4.052-1ubuntu3.1+esm14","2:7.4.052-1ubuntu3.1+esm15","2:7.4.052-1ubuntu3.1+esm16","2:7.4.052-1ubuntu3.1+esm17","2:7.4.052-1ubuntu3.1+esm18","2:7.4.052-1ubuntu3.1+esm19","2:7.4.052-1ubuntu3.1+esm20","2:7.4.052-1ubuntu3.1+esm21"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-55158.json"}},{"package":{"name":"vim","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/vim@2:7.4.1689-3ubuntu1.5+esm27?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:7.4.712-2ubuntu4","2:7.4.826-1ubuntu1","2:7.4.826-1ubuntu2","2:7.4.826-1ubuntu3","2:7.4.963-1ubuntu1","2:7.4.963-1ubuntu4","2:7.4.963-1ubuntu5","2:7.4.1689-3ubuntu1","2:7.4.1689-3ubuntu1.1","2:7.4.1689-3ubuntu1.2","2:7.4.1689-3ubuntu1.3","2:7.4.1689-3ubuntu1.4","2:7.4.1689-3ubuntu1.5","2:7.4.1689-3ubuntu1.5+esm2","2:7.4.1689-3ubuntu1.5+esm3","2:7.4.1689-3ubuntu1.5+esm4","2:7.4.1689-3ubuntu1.5+esm5","2:7.4.1689-3ubuntu1.5+esm6","2:7.4.1689-3ubuntu1.5+esm7","2:7.4.1689-3ubuntu1.5+esm8","2:7.4.1689-3ubuntu1.5+esm10","2:7.4.1689-3ubuntu1.5+esm11","2:7.4.1689-3ubuntu1.5+esm12","2:7.4.1689-3ubuntu1.5+esm13","2:7.4.1689-3ubuntu1.5+esm14","2:7.4.1689-3ubuntu1.5+esm15","2:7.4.1689-3ubuntu1.5+esm17","2:7.4.1689-3ubuntu1.5+esm18","2:7.4.1689-3ubuntu1.5+esm19","2:7.4.1689-3ubuntu1.5+esm20","2:7.4.1689-3ubuntu1.5+esm22","2:7.4.1689-3ubuntu1.5+esm23","2:7.4.1689-3ubuntu1.5+esm24","2:7.4.1689-3ubuntu1.5+esm25","2:7.4.1689-3ubuntu1.5+esm26","2:7.4.1689-3ubuntu1.5+esm27"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-55158.json"}},{"package":{"name":"vim","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/vim@2:8.0.1453-1ubuntu1.13+esm12?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:8.0.0197-4ubuntu5","2:8.0.1144-1ubuntu1","2:8.0.1401-1ubuntu1","2:8.0.1401-1ubuntu2","2:8.0.1401-1ubuntu3","2:8.0.1453-1ubuntu1","2:8.0.1453-1ubuntu1.1","2:8.0.1453-1ubuntu1.3","2:8.0.1453-1ubuntu1.4","2:8.0.1453-1ubuntu1.6","2:8.0.1453-1ubuntu1.7","2:8.0.1453-1ubuntu1.8","2:8.0.1453-1ubuntu1.9","2:8.0.1453-1ubuntu1.10","2:8.0.1453-1ubuntu1.11","2:8.0.1453-1ubuntu1.12","2:8.0.1453-1ubuntu1.13","2:8.0.1453-1ubuntu1.13+esm1","2:8.0.1453-1ubuntu1.13+esm3","2:8.0.1453-1ubuntu1.13+esm4","2:8.0.1453-1ubuntu1.13+esm5","2:8.0.1453-1ubuntu1.13+esm6","2:8.0.1453-1ubuntu1.13+esm7","2:8.0.1453-1ubuntu1.13+esm8","2:8.0.1453-1ubuntu1.13+esm9","2:8.0.1453-1ubuntu1.13+esm10","2:8.0.1453-1ubuntu1.13+esm11","2:8.0.1453-1ubuntu1.13+esm12"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-55158.json"}},{"package":{"name":"vim","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/vim@2:8.1.2269-1ubuntu5.32?arch=source&distro=esm-infra/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:8.1.0875-5ubuntu2","2:8.1.0875-5ubuntu3","2:8.1.0875-5ubuntu4","2:8.1.2269-1ubuntu1","2:8.1.2269-1ubuntu4","2:8.1.2269-1ubuntu5","2:8.1.2269-1ubuntu5.3","2:8.1.2269-1ubuntu5.4","2:8.1.2269-1ubuntu5.6","2:8.1.2269-1ubuntu5.7","2:8.1.2269-1ubuntu5.8","2:8.1.2269-1ubuntu5.9","2:8.1.2269-1ubuntu5.11","2:8.1.2269-1ubuntu5.12","2:8.1.2269-1ubuntu5.13","2:8.1.2269-1ubuntu5.14","2:8.1.2269-1ubuntu5.15","2:8.1.2269-1ubuntu5.16","2:8.1.2269-1ubuntu5.17","2:8.1.2269-1ubuntu5.18","2:8.1.2269-1ubuntu5.20","2:8.1.2269-1ubuntu5.21","2:8.1.2269-1ubuntu5.22","2:8.1.2269-1ubuntu5.23","2:8.1.2269-1ubuntu5.24","2:8.1.2269-1ubuntu5.25","2:8.1.2269-1ubuntu5.26","2:8.1.2269-1ubuntu5.29","2:8.1.2269-1ubuntu5.30","2:8.1.
