CVE-2026-52954

In the Linux kernel, the following vulnerability has been resolved: libceph: handle rbtree insertion error in decodechooseargs A message of type CEPHMSGOSDMAP contains an OSD map that itself contains a CRUSH map. The received CRUSH map may optionally contain chooseargs that get decoded in...

CVE-2026-52957

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential null-ptr-deref in decodechooseargs A message of type CEPHMSGOSDMAP contains an OSD map that itself contains a CRUSH map. When decoding this CRUSH map in crushdecode, an array of maxbuckets CRUSH buckets is...

CVE-2026-52957

Consolidated details from CVE-2026-52957 show a Linux kernel libceph flaw in processing CEPH_MSG_OSD_MAP: during CRUSH map decoding, bucket indices may reference NULL buckets when decoding crush_choose_arg_map, risking a NULL pointer dereference. A patch extends the validation to only access non-...
