{"id":"CVE-2026-68468","summary":"mtd: virt-concat: free duplicate generated name","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: virt-concat: free duplicate generated name\n\nEvery MTD registration runs mtd_virt_concat_create_join().  Once a\nvirtual concat has already been registered, the function builds the same\nname again and takes the equal-name branch.  That branch skips to the\nnext item without freeing the newly allocated string.\n\nFree the temporary name before continuing.","modified":"2026-08-18T03:30:52.439895410Z","published":"2026-08-15T05:51:26.686Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68468.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e65079d28e5c461b6813ea5821be4dfff24ff63"},{"type":"WEB","url":"https://git.kernel.org/stable/c/caa0ecbeff4f7fbf70f22bd8ca598918bffb1b78"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68468.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68468"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"43db6366fc2de02050e66389f5628d3fdc9af10a"},{"fixed":"0e65079d28e5c461b6813ea5821be4dfff24ff63"},{"fixed":"caa0ecbeff4f7fbf70f22bd8ca598918bffb1b78"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68468.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68468.json"}}],"schema_version":"1.9.0"}
