{"id":"CVE-2026-23123","summary":"interconnect: debugfs: initialize src_node and dst_node to empty strings","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ninterconnect: debugfs: initialize src_node and dst_node to empty strings\n\nThe debugfs_create_str() API assumes that the string pointer is either NULL\nor points to valid kmalloc() memory. Leaving the pointer uninitialized can\ncause problems.\n\nInitialize src_node and dst_node to empty strings before creating the\ndebugfs entries to guarantee that reads and writes are safe.","modified":"2026-04-02T17:30:25.696815404Z","published":"2026-02-14T15:09:53.369Z","related":["SUSE-SU-2026:20838-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23123.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5d7c7e1fb3ec24fdd0f9faa27b666d6789e891e8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8cc27f5c6dd17dd090f3a696683f04336c162ff5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/935d0938b570589c8b0a1733d2cba3c39d027f25"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa79a5a959c7c414bd6fba01ea8dbaddd44f13e7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23123.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23123"},{"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":"770c69f037c18cfaa37c3d6c6ef8bd257635513f"},{"fixed":"aa79a5a959c7c414bd6fba01ea8dbaddd44f13e7"},{"fixed":"935d0938b570589c8b0a1733d2cba3c39d027f25"},{"fixed":"5d7c7e1fb3ec24fdd0f9faa27b666d6789e891e8"},{"fixed":"8cc27f5c6dd17dd090f3a696683f04336c162ff5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23123.json"}}],"schema_version":"1.7.5"}
