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...
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...

kernel: libceph: prevent potential out-of-bounds reads in handle_auth_done()
In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-bounds reads in handleauthdone Perform an explicit bounds check on payloadlen to avoid a possible out-of-bounds access in the callout. idryomov: changelog...
kernel: libceph: make decode_pool() more resilient against corrupted osdmaps
In the Linux kernel, the following vulnerability has been resolved: libceph: make decodepool more resilient against corrupted osdmaps If the osdmap is maliciously corrupted such that the encoded length of cephpgpool envelope is less than what is expected for a particular encoding version,...
kernel: libceph: replace overzealous BUG_ON in osdmap_apply_incremental()
In the Linux kernel, the following vulnerability has been resolved: libceph: replace overzealous BUGON in osdmapapplyincremental If the osdmap is maliciously corrupted such that the incremental osdmap epoch is different from what is expected, there is no need to BUG. Instead, just declare the...
RHEL 9 : kernel (RHSA-2026:27735)
The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:27735 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: libceph: make decodepool more...
Astra Linux – Vulnerability in Linux 6.1
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 5.10, Linux 6.1
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 in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: libceph: The state of sparse-read was reset in osdfault. When a fault occurs, the connection is abandoned, re-established, and any pending operations are retried. The OSD client tracks the progress of a sparse-read reply using a...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: libceph: Potential out-of-bounds reads in processmessageheader have been prevented. If the message frame is maliciously corrupted in such a way that the length of the control segment becomes shorter than the size of the message...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: libceph: Use u32 for non-negative values in cephmonmapDecode This patch fixes unnecessary implicit conversions that change the signedness of bloblen and nummon in cephmonmapDecode. Currently, bloblen and nummon are signed int...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: libceph: Potential out-of-bounds writes have been prevented in the handleauthsessionkey function. The len field originates from untrusted network packets. Boundary checks have been added to prevent potential out-of-bounds writes...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: libceph: prevented potential out-of-bounds reads in handleauthdone A explicit bounds check was performed on payloadlen to avoid possible out-of-bounds accesses during the callout. idryomov: changelog...
