{"id":"CVE-2024-53690","summary":"nilfs2: prevent use of deleted inode","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: prevent use of deleted inode\n\nsyzbot reported a WARNING in nilfs_rmdir. [1]\n\nBecause the inode bitmap is corrupted, an inode with an inode number that\nshould exist as a \".nilfs\" file was reassigned by nilfs_mkdir for \"file0\",\ncausing an inode duplication during execution.  And this causes an\nunderflow of i_nlink in rmdir operations.\n\nThe inode is used twice by the same task to unmount and remove directories\n\".nilfs\" and \"file0\", it trigger warning in nilfs_rmdir.\n\nAvoid to this issue, check i_nlink in nilfs_iget(), if it is 0, it means\nthat this inode has been deleted, and iput is executed to reclaim it.\n\n[1]\nWARNING: CPU: 1 PID: 5824 at fs/inode.c:407 drop_nlink+0xc4/0x110 fs/inode.c:407\n...\nCall Trace:\n \u003cTASK\u003e\n nilfs_rmdir+0x1b0/0x250 fs/nilfs2/namei.c:342\n vfs_rmdir+0x3a3/0x510 fs/namei.c:4394\n do_rmdir+0x3b5/0x580 fs/namei.c:4453\n __do_sys_rmdir fs/namei.c:4472 [inline]\n __se_sys_rmdir fs/namei.c:4470 [inline]\n __x64_sys_rmdir+0x47/0x50 fs/namei.c:4470\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x77/0x7f","modified":"2026-04-16T00:08:24.122507625Z","published":"2025-01-11T12:35:40.934Z","related":["SUSE-SU-2025:0289-1","SUSE-SU-2025:0428-1","SUSE-SU-2025:0499-1","SUSE-SU-2025:0556-1","SUSE-SU-2025:0557-1","SUSE-SU-2025:0577-1","SUSE-SU-2025:0577-2","SUSE-SU-2025:20165-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20248-1","SUSE-SU-2025:20249-1","USN-7379-2","USN-7380-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53690.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/284760b320a0bac411b18108316939707dccb12b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/55e4baa0d32f0530ddc64c26620e1f2f8fa2724c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d4ed71327b0b5f3b179a19dc3c06be9509ab3db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/901ce9705fbb9f330ff1f19600e5daf9770b0175"},{"type":"WEB","url":"https://git.kernel.org/stable/c/912188316a8c9e41b8c1603c2276a05043b14f96"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef942d233643777f7b2a5deef620e82942983143"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff561987ff12b6a3233431ff659b5d332e22f153"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53690.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53690"},{"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":"d25006523d0b9e49fd097b2e974e7c8c05bd7f54"},{"fixed":"55e4baa0d32f0530ddc64c26620e1f2f8fa2724c"},{"fixed":"5d4ed71327b0b5f3b179a19dc3c06be9509ab3db"},{"fixed":"912188316a8c9e41b8c1603c2276a05043b14f96"},{"fixed":"ef942d233643777f7b2a5deef620e82942983143"},{"fixed":"284760b320a0bac411b18108316939707dccb12b"},{"fixed":"ff561987ff12b6a3233431ff659b5d332e22f153"},{"fixed":"901ce9705fbb9f330ff1f19600e5daf9770b0175"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-53690.json"}}],"schema_version":"1.7.5"}
