CVE-2026-89653

A vulnerability in the Linux kernel's Ceph filesystem allows an out-of-bounds write during MDSMap decoding. The MDSMap export_targets entries are monitor-controlled , and the check_new_map() function uses each entry as a bit number in a fixed stack bitmap. A rank value ≥ CEPH_MAX_MDS causes set_b...

CVE-2026-89649

This out-of-bounds read affects the Linux kernel's CephFS client , specifically the __build_xattrs() function. When decoding the xattr blob supplied by a Ceph metadata server (MDS), the 32-bit value length of the final attribute is never validated against the blob size via a ceph_decode_need() ch...
