{"id":"CVE-2025-38328","summary":"jffs2: check jffs2_prealloc_raw_node_refs() result in few other places","details":"In the Linux kernel, the following vulnerability has been resolved:\n\njffs2: check jffs2_prealloc_raw_node_refs() result in few other places\n\nFuzzing hit another invalid pointer dereference due to the lack of\nchecking whether jffs2_prealloc_raw_node_refs() completed successfully.\nSubsequent logic implies that the node refs have been allocated.\n\nHandle that. The code is ready for propagating the error upwards.\n\nKASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]\nCPU: 1 PID: 5835 Comm: syz-executor145 Not tainted 5.10.234-syzkaller #0\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014\nRIP: 0010:jffs2_link_node_ref+0xac/0x690 fs/jffs2/nodelist.c:600\nCall Trace:\n jffs2_mark_erased_block fs/jffs2/erase.c:460 [inline]\n jffs2_erase_pending_blocks+0x688/0x1860 fs/jffs2/erase.c:118\n jffs2_garbage_collect_pass+0x638/0x1a00 fs/jffs2/gc.c:253\n jffs2_reserve_space+0x3f4/0xad0 fs/jffs2/nodemgmt.c:167\n jffs2_write_inode_range+0x246/0xb50 fs/jffs2/write.c:362\n jffs2_write_end+0x712/0x1110 fs/jffs2/file.c:302\n generic_perform_write+0x2c2/0x500 mm/filemap.c:3347\n __generic_file_write_iter+0x252/0x610 mm/filemap.c:3465\n generic_file_write_iter+0xdb/0x230 mm/filemap.c:3497\n call_write_iter include/linux/fs.h:2039 [inline]\n do_iter_readv_writev+0x46d/0x750 fs/read_write.c:740\n do_iter_write+0x18c/0x710 fs/read_write.c:866\n vfs_writev+0x1db/0x6a0 fs/read_write.c:939\n do_pwritev fs/read_write.c:1036 [inline]\n __do_sys_pwritev fs/read_write.c:1083 [inline]\n __se_sys_pwritev fs/read_write.c:1078 [inline]\n __x64_sys_pwritev+0x235/0x310 fs/read_write.c:1078\n do_syscall_64+0x30/0x40 arch/x86/entry/common.c:46\n entry_SYSCALL_64_after_hwframe+0x67/0xd1\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller.","modified":"2026-04-16T04:32:16.781032471Z","published":"2025-07-10T08:15:02.296Z","related":["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-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38328.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/042fa922c84b5080401bcd8897d4ac4919d15075"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b6d96503255a3ed676cd70f8368870c6d6a25c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/38d767fb4a7766ec2058f97787e4c6e8d10343d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e860296d7808de1db175c1eda29f94a2955dcc4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cd42ddddd70abc7127c12b96c8c85dbd080ea56f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d1b81776f337a9b997f797c70ac0a26d838a2168"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d96e6451a8d0fe62492d4cc942d695772293c05a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f41c625328777f9ad572901ba0b0065bb9c9c1da"},{"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-2025-38328.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38328"},{"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":"2f785402f39b96a077b6e62bf26164bfb8e0c980"},{"fixed":"7e860296d7808de1db175c1eda29f94a2955dcc4"},{"fixed":"d96e6451a8d0fe62492d4cc942d695772293c05a"},{"fixed":"f41c625328777f9ad572901ba0b0065bb9c9c1da"},{"fixed":"38d767fb4a7766ec2058f97787e4c6e8d10343d6"},{"fixed":"cd42ddddd70abc7127c12b96c8c85dbd080ea56f"},{"fixed":"d1b81776f337a9b997f797c70ac0a26d838a2168"},{"fixed":"042fa922c84b5080401bcd8897d4ac4919d15075"},{"fixed":"2b6d96503255a3ed676cd70f8368870c6d6a25c6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38328.json"}}],"schema_version":"1.7.5"}
