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-2026-89651 ceph: bound MDSCapAuth path and fs_name decode in handle_session()

In the Linux kernel, the following vulnerability has been resolved: ceph: bound MDSCapAuth path and fsname decode in handlesession handlesession decodes the MDSCapAuth records carried by a CEPHSESSIONOPEN message msgversion = 6. For each record the match.path and match.fsname byte strings are rea...

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...

In the Linux kernel, the following vulnerability has been resolved: nfsd: cap decoded POSIX ACL count to bound sort cost nfsd4 decode posixacl reads a u32 entry count off the wire and passes it straight to posix acl alloc and sort pacl range. The latter is an On^2 bubble sort, so a client-chosen...

PT-2026-90372

In the Linux kernel, the following vulnerability has been resolved: libceph: reject buckets with mismatched CRUSH ids crush decode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from the decoded bucket id. A malformed map can therefore make one bucke...
