{"id":"CVE-2023-52448","summary":"gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump\n\nSyzkaller has reported a NULL pointer dereference when accessing\nrgd-\u003erd_rgl in gfs2_rgrp_dump().  This can happen when creating\nrgd-\u003erd_gl fails in read_rindex_entry().  Add a NULL pointer check in\ngfs2_rgrp_dump() to prevent that.","modified":"2026-04-02T09:42:47.620775Z","published":"2024-02-22T16:21:39.915Z","related":["ALSA-2024:2394","SUSE-SU-2024:0855-1","SUSE-SU-2024:0856-1","SUSE-SU-2024:0857-1","SUSE-SU-2024:0858-1","SUSE-SU-2024:0900-1","SUSE-SU-2024:0900-2","SUSE-SU-2024:0910-1","SUSE-SU-2024:0926-1","SUSE-SU-2024:0977-1","USN-6818-2","USN-6819-2"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52448.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/067a7c48c2c70f05f9460d6f0e8423e234729f05"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c28478af371a1c3fdb570ca67f110e1ae60fc37"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8877243beafa7c6bfc42022cbfdf9e39b25bd4fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c323efd620c741168c8e0cc6fc0be04ab57e331a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d69d7804cf9e2ba171a27e5f98bc266f13d0414a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ee0586d73cbaf0e7058bc640d62a9daf2dfa9178"},{"type":"WEB","url":"https://git.kernel.org/stable/c/efc8ef87ab9185a23d5676f2f7d986022d91bcde"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52448.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52448"},{"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":"72244b6bc752b5c496f09de9a13c18adc314a53c"},{"fixed":"efc8ef87ab9185a23d5676f2f7d986022d91bcde"},{"fixed":"5c28478af371a1c3fdb570ca67f110e1ae60fc37"},{"fixed":"ee0586d73cbaf0e7058bc640d62a9daf2dfa9178"},{"fixed":"d69d7804cf9e2ba171a27e5f98bc266f13d0414a"},{"fixed":"067a7c48c2c70f05f9460d6f0e8423e234729f05"},{"fixed":"c323efd620c741168c8e0cc6fc0be04ab57e331a"},{"fixed":"8877243beafa7c6bfc42022cbfdf9e39b25bd4fa"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-52448.json"}}],"schema_version":"1.7.5"}
