{"id":"CVE-2026-98885","summary":"ima: return error early if file xattr cannot be changed","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nima: return error early if file xattr cannot be changed\n\nDuring early boot, the filesystem is read-only and any changes\nto xattrs are not allowed. This fails in case of ext4 because\nchanging xattr starts an ext4 transaction which fails with the\nfollowing warning.\n\nWARNING: fs/ext4/ext4_jbd2.c:75 at ext4_journal_check_start+0x63/0xa0 [ext4], CPU#1: systemd-sysroot/561\nCPU: 1 UID: 0 PID: 561 Comm: systemd-sysroot Not tainted 6.19.12-1-default #1 PREEMPT(voluntary) openSUSE Tumbleweed  c2dfc3c9d9f6f1233251c5d4410574fe82a348ee\nHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS unknown 02/02/2022\nRIP: 0010:ext4_journal_check_start+0x63/0xa0 [ext4]\nCall Trace:\n  __ext4_journal_start_sb+0x3e/0x180 [ext4 6d025f3bc52c89a957b89a89d211fadf5e9434e1]\n  ext4_xattr_set+0x104/0x150 [ext4 6d025f3bc52c89a957b89a89d211fadf5e9434e1]\n  __vfs_setxattr+0x9a/0xd0\n  __vfs_setxattr_noperm+0x76/0x1f0\n  ima_appraise_measurement+0x23e/0xe40\n  ima_d_path+0x5a/0xd0\n  process_measurement+0xb29/0xc40\n  ? copy_from_kernel_nofault+0x21/0xe0\n  ? fscrypt_file_open+0xc0/0xe0\n  ? ext4_file_open+0x60/0x490 [ext4 6d025f3bc52c89a957b89a89d211fadf5e9434e1]\n  ? bpf_prog_31efb7c56239148b_restrict_filesystems+0xab/0x126\n  ? __bpf_prog_exit+0x23/0xd0\n  ? __bpf_tramp_exit+0xd/0x50\n  ? bpf_trampoline_6442530367+0x9f/0xea\n  ima_file_check+0x57/0x80\n  security_file_post_open+0x50/0xf0\n  path_openat+0x493/0x1650\n  do_filp_open+0xc7/0x170\n\nDetect the state of the file early and return the error.","modified":"2026-11-12T17:29:24.285372853Z","published":"2026-10-23T11:37:41.736Z","related":["SUSE-SU-2026:24643-1","SUSE-SU-2026:24648-1","SUSE-SU-2026:24651-1","SUSE-SU-2026:24662-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98885.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2f29f880e98bf0087215726c45a485afd15b42cf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4d98295357bcacb70874e73117e298a9d7d9b830"},{"type":"WEB","url":"https://git.kernel.org/stable/c/69fc6474236d9edda6983623e4282f2bdfd8e3d8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/86acb68ebb220b83def94e7f4c33e24e843970e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c77312728d07b60fc028f676e42d842df918bcd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6988714c0549e06610635c7a71e88635da6db64"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dce1b66fcfb40c935f426f602c3a41a7b9f62ba4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98885.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98885"},{"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":"07f6a79415d7d502ee0c7d02ace6594a7be7429a"},{"fixed":"86acb68ebb220b83def94e7f4c33e24e843970e0"},{"fixed":"4d98295357bcacb70874e73117e298a9d7d9b830"},{"fixed":"c6988714c0549e06610635c7a71e88635da6db64"},{"fixed":"8c77312728d07b60fc028f676e42d842df918bcd"},{"fixed":"dce1b66fcfb40c935f426f602c3a41a7b9f62ba4"},{"fixed":"2f29f880e98bf0087215726c45a485afd15b42cf"},{"fixed":"69fc6474236d9edda6983623e4282f2bdfd8e3d8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98885.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.7.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98885.json"}}],"schema_version":"1.9.2"}
