The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001861 advisory. Buffer overflow in net/ceph/authx.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service memory corruption and...

CVE-2025-71116

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,...

CVE-2025-71116

The CVE-2025-71116 issue concerns the Linux kernel’s libceph decode_pool() handling of osdmaps. When an osdmap is maliciously corrupted such that the encoded length for a ceph_pg_pool envelope is smaller than expected, an out-of-bounds read could occur because the existing bounds check relied sol...

Astra Linux – Vulnerability in Ceph

Ceph is a distributed object, block, and file storage platform. In versions up to and including 19.2.3, using the x-amz-copy-source argument to copy an object and specifying an empty string as its content resulted in the RGW daemon crashing, leading to a DoS attack. As of the time of publication,...

Astra Linux – Vulnerability in Ceph

Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and earlier, it is possible to send a JWT with “none” as its JWT algorithm. By doing this, the JWT signature is not checked. The vulnerability lies most likely in the RadosGW OIDC provider. As of the time of...
