发布于3月6日3月6日 Members VMware Photon OS: CVE-2023-52760 Severity 7 CVSS (AV:L/AC:L/Au:S/C:C/I:C/A:C) Published 05/21/2024 Created 01/21/2025 Added 01/20/2025 Modified 02/04/2025 Description In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix slab-use-after-free in gfs2_qd_dealloc In gfs2_put_super(), whether withdrawn or not, the quota should be cleaned up by gfs2_quota_cleanup(). Otherwise, struct gfs2_sbd will be freed before gfs2_qd_dealloc (rcu callback) has run for all gfs2_quota_data objects, resulting in use-after-free. Also, gfs2_destroy_threads() and gfs2_quota_cleanup() is already called by gfs2_make_fs_ro(), so in gfs2_put_super(), after calling gfs2_make_fs_ro(), there is no need to call them again.
