{"id":"CVE-2026-45922","summary":"RDMA/mlx5: Fix memory leak in GET_DATA_DIRECT_SYSFS_PATH handler","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Fix memory leak in GET_DATA_DIRECT_SYSFS_PATH handler\n\nThe UVERBS_HANDLER(MLX5_IB_METHOD_GET_DATA_DIRECT_SYSFS_PATH) function\nallocates memory for the device path using kobject_get_path(). If the\nlength of the device path exceeds the output buffer length, the function\nreturns -ENOSPC but does not free the allocated memory, resulting in a\nmemory leak.\n\nAdd a kfree() call to the error path to ensure the allocated memory is\nproperly freed.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.","modified":"2026-07-08T08:13:33.100667978Z","published":"2026-05-27T12:17:41.431Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45922.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/9b9d253908478f504297ac283c514e5953ddafa6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b2bc649c18fbe8a7fd38d17266da3dcbfbcc44d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b3a10eca24fcfe913c0875e620f19596001bd6dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ee998cdbff6680891b0efd9d6ce53a388e5342c3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45922.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45922"},{"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":"ec7ad6530909983c8736c80af46e3529ce7bab55"},{"fixed":"ee998cdbff6680891b0efd9d6ce53a388e5342c3"},{"fixed":"b2bc649c18fbe8a7fd38d17266da3dcbfbcc44d2"},{"fixed":"b3a10eca24fcfe913c0875e620f19596001bd6dc"},{"fixed":"9b9d253908478f504297ac283c514e5953ddafa6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45922.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45922.json"}}],"schema_version":"1.7.5"}
