This causes the subsequent call to\nntfs_fs_free() to skip freeing the ntfs_mount_options structure.\n\nThis results in a kmemleak report:\n\n  unreferenced object 0xff1100015378b800 (size 32):\n    comm \"mount\", pid 582, jiffies 4294890685\n    hex dump (first 32 bytes):\n      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n      00 00 00 00 00 00 00 00 ed ff ed ff 00 04 00 00  ................\n    backtrace (crc ed541d8c):\n      __kmalloc_cache_noprof+0x424/0x5a0\n      __ntfs_init_fs_context+0x47/0x590\n      alloc_fs_context+0x5d8/0x960\n      __x64_sys_fsopen+0xb1/0x190\n      do_syscall_64+0x50/0x1f0\n      entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nThis issue can be reproduced using the following commands:\n        fallocate -l 100M test.file\n        mount test.file /tmp/test\n\nSince sbi->options is duplicated from fc->fs_private and does not\ndirectly use the memory allocated for fs_private, it is unnecessary to\nset fc->fs_private to NULL.\n\nAdditionally, this patch simplifies the code by utilizing the helper\nfunction put_mount_options() instead of open-coding the cleanup logic.","state":0,"publishedAt":"2026-05-27T12:24:03.532+00:00","modifiedAt":"2026-05-27T12:24:03.532+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"fs/ntfs3/super.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"aee4d5a521e94f658e46c904e08a473daa9c8fc0\",\n                            \"lessThan\": \"dac871d833b09495198dcac81d2ebaa8db11acbc\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"aee4d5a521e94f658e46c904e08a473daa9c8fc0\",\n                            \"lessThan\": \"f7edab0cee03a1cbe0e55a7bcab8d2d8b6b74278\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"fs/ntfs3/super.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.19.4\",\n                            \"lessThanOrEqual\": \"6.19.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.0\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/dac871d833b09495198dcac81d2ebaa8db11acbc","https://git.kernel.org/stable/c/f7edab0cee03a1cbe0e55a7bcab8d2d8b6b74278"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-71312","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-71312","identifiers":["CVE-2025-71312"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
