{"id":"CVE-2025-38313","summary":"bus: fsl-mc: fix double-free on mc_dev","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbus: fsl-mc: fix double-free on mc_dev\n\nThe blamed commit tried to simplify how the deallocations are done but,\nin the process, introduced a double-free on the mc_dev variable.\n\nIn case the MC device is a DPRC, a new mc_bus is allocated and the\nmc_dev variable is just a reference to one of its fields. In this\ncircumstance, on the error path only the mc_bus should be freed.\n\nThis commit introduces back the following checkpatch warning which is a\nfalse-positive.\n\nWARNING: kfree(NULL) is safe and this check is probably not required\n+       if (mc_bus)\n+               kfree(mc_bus);","modified":"2026-03-20T12:42:48.049174Z","published":"2025-07-10T07:42:21.314Z","related":["MGASA-2025-0218","MGASA-2025-0219","SUSE-SU-2025:02853-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:02969-1","SUSE-SU-2025:02996-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:03023-1","SUSE-SU-2025:03204-1","SUSE-SU-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","openSUSE-SU-2025:20081-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38313.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/12e4431e5078847791936820bd39df9e1ee26d2e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1d5baab39e5b09a76870b345cdee7933871b881f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3135e03a92f6b5259d0a7f25f728e9e7866ede3f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4b23c46eb2d88924b93aca647bde9a4b9cf62cf9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7002b954c4a8b9965ba0f139812ee4a6f71beac8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/873d47114fd5e5a1cad2018843671537cc71ac84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b2057374f326303c86d8423415ab58656eebc695"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d694bf8a9acdbd061596f3e7549bc8cb70750a60"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38313.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38313"},{"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":"a042fbed02904493ae6df26ec836045f5a7d3ce2"},{"fixed":"12e4431e5078847791936820bd39df9e1ee26d2e"},{"fixed":"3135e03a92f6b5259d0a7f25f728e9e7866ede3f"},{"fixed":"7002b954c4a8b9965ba0f139812ee4a6f71beac8"},{"fixed":"b2057374f326303c86d8423415ab58656eebc695"},{"fixed":"4b23c46eb2d88924b93aca647bde9a4b9cf62cf9"},{"fixed":"1d5baab39e5b09a76870b345cdee7933871b881f"},{"fixed":"873d47114fd5e5a1cad2018843671537cc71ac84"},{"fixed":"d694bf8a9acdbd061596f3e7549bc8cb70750a60"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38313.json"}}],"schema_version":"1.7.5"}
