{"id":"CVE-2025-39743","summary":"jfs: truncate good inode pages when hard link is 0","details":"In the Linux kernel, the following vulnerability has been resolved:\n\njfs: truncate good inode pages when hard link is 0\n\nThe fileset value of the inode copy from the disk by the reproducer is\nAGGR_RESERVED_I. When executing evict, its hard link number is 0, so its\ninode pages are not truncated. This causes the bugon to be triggered when\nexecuting clear_inode() because nrpages is greater than 0.","modified":"2026-04-02T12:48:08.115547Z","published":"2025-09-11T16:52:17.043Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4141-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39743.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1bb5cdc3e39f0c2b311fcb631258b7e60d3fb0d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b1d5ca395a5fb170c3f885cd42c16179f7f54ec"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2d91b3765cd05016335cd5df5e5c6a29708ec058"},{"type":"WEB","url":"https://git.kernel.org/stable/c/34d8e982bac48bdcca7524644a8825a580edce74"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5845b926c561b8333cd65169526eec357d7bb449"},{"type":"WEB","url":"https://git.kernel.org/stable/c/89fff8e3d6710fc32507b8e19eb5afa9fb79b896"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8ed7275910fb7177012619864e04d3008763f3ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5b471820c33365a8ccd2d463578bf4e47056c2c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df3fd8daf278eca365f221749ae5b728e8382a04"},{"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/2025/39xxx/CVE-2025-39743.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-39743"},{"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":"32983696a48a6c41d99f3eca82ba7510a552d843"},{"fixed":"89fff8e3d6710fc32507b8e19eb5afa9fb79b896"},{"fixed":"5845b926c561b8333cd65169526eec357d7bb449"},{"fixed":"8ed7275910fb7177012619864e04d3008763f3ea"},{"fixed":"b5b471820c33365a8ccd2d463578bf4e47056c2c"},{"fixed":"34d8e982bac48bdcca7524644a8825a580edce74"},{"fixed":"df3fd8daf278eca365f221749ae5b728e8382a04"},{"fixed":"2b1d5ca395a5fb170c3f885cd42c16179f7f54ec"},{"fixed":"1bb5cdc3e39f0c2b311fcb631258b7e60d3fb0d3"},{"fixed":"2d91b3765cd05016335cd5df5e5c6a29708ec058"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-39743.json"}}],"schema_version":"1.7.5"}
