{"id":"CVE-2018-13093","details":"An issue was discovered in fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3. There is a NULL pointer dereference and panic in lookup_slow() on a NULL inode-\u003ei_ops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that cached inodes are free during allocation.","modified":"2026-03-12T22:47:04.690888Z","published":"2018-07-03T10:29:00.223Z","related":["SUSE-SU-2018:2775-1","SUSE-SU-2018:2776-1","SUSE-SU-2018:2858-1","SUSE-SU-2018:2862-1","SUSE-SU-2018:2908-1","SUSE-SU-2018:2908-2","SUSE-SU-2018:2980-1","SUSE-SU-2018:2981-1","SUSE-SU-2018:3083-1","SUSE-SU-2018:3084-1","SUSE-SU-2018:3961-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html"},{"type":"WEB","url":"https://usn.ubuntu.com/4094-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4118-1/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2029"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2043"},{"type":"REPORT","url":"https://bugzilla.kernel.org/show_bug.cgi?id=199367"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/commit/?h=for-next&id=afca6c5b2595fc44383919fba740c194b0b76aff"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/afca6c5b2595fc44383919fba740c194b0b76aff"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.17.3"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-13093.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
