CVE-2026-52957 libceph: Fix potential null-ptr-deref in decode_choose_args()
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-2026-52958
CVE-2026-52958 affects the Linux kernel libceph subsystem. The vulnerability arises in osdmap_decode() when decoding osd_state and osd_weight for each osd; the ceph_decode_need() check did not account for map->max_osd*sizeof(*map->osd_weight), enabling a potential out-of-bounds memory acces...
CVE-2026-52958
In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in osdmapdecode When decoding osdstate and osdweight from an incoming osdmap in osdmapdecode, both are decoded for each osd, i.e., map-maxosd times. The cephdecodeneed check only accoun...
CVE-2026-52956 libceph: Fix potential out-of-bounds access in __ceph_x_decrypt()
In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in cephxdecrypt In cephxdecrypt, a part of the buffer p is interpreted as a cephxencryptheader, and the magic field of this struct is accessed. This happens without any guarantee that t...
CVE-2026-52956
The CVE-2026-52956 issue affects the Linux kernel’s libceph code, specifically __ceph_x_decrypt(), where a buffer region can be misinterpreted as a ceph_x_encrypt_header and hdr->magic accessed without ensuring sufficient plaintext size. This can trigger an out-of-bounds memory access when cip...

CVE-2026-52955
In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in crushdecode A message of type CEPHMSGOSDMAP containing a crush map with at least one bucket has two fields holding the bucket algorithm. If the values in these two fields differ, an...
CVE-2026-52955
The CVE-2026-52955 vulnerability affects the Linux kernel’s libceph crush_decode(). A CEPH_MSG_OSD_MAP containing a crush map with at least one bucket could have two bucket algorithm fields (alg and b->alg) that differ, leading to potential out-of-bounds access during allocation or destruction...
CVE-2026-52954
The CVE-2026-52954 issue affects the Linux kernel libceph component. A crafted CEPH_MSG_OSD_MAP can carry a CRUSH map with two crush_choose_arg_maps sharing the same index, causing an assertion in insert_choose_arg_map() to trigger a kernel BUG when inserting the second entry. The vulnerability c...
CVE-2026-52954 libceph: handle rbtree insertion error in decode_choose_args()
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...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: libceph: Defined and enforced the CEPHMAXKEYLEN. When decoding the key, verify that the key material fits into a fixed-size buffer in processauthdone, and that its length is reasonable. The new CEPHMAXKEYLEN check replaces the...
Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerabilities have been resolved: libceph: fixed a potential use-after-free in havemonandosdmap The wait loop in cephopensession can race with the client receiving a new monmap or osdmap shortly after the initial map is received. Both cephmonchandlemap and...
Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: libceph: Replace BUGON with a bounds check for map-maxosd. OSD indexes come from untrusted network packets. Boundaries checks are added to validate these against map-maxosd. idryomov: removed BUGON in cephgetprimaryaffinity, mino...
Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
