CVE-2026-89652

CVE-2026-89652 is a slab out-of-bounds write in the Linux kernel's Ceph filesystem (cephfs). The functions ceph_get_name() and __get_snap_name() copy an MDS-supplied dentry name into a NAME_MAX-sized buffer via memcpy without validating the length, allowing a malicious or buggy Ceph MDS to overfl...
