The vulnerability of the osd_fault() function in the net/ceph/osd_client.c module, which is part of the Linux kernel’s networking functions, allows a hacker to trigger a service failure.

The vulnerability of the osdfault function in the net/ceph/osdclient.c module, which implements kernel networking functions in the Linux operating system, is related to state management errors. Exploiting this vulnerability could allow a remote attacker to cause service failures...

The vulnerability in the ceph/osd_client.c component of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability in the ceph/osdclient.c component of the Linux operating system is related to errors during thread blocking. Exploiting this vulnerability can allow an attacker to cause a service failure...

UBUNTU-CVE-2026-68082

In the Linux kernel, the following vulnerability has been resolved: libceph: fix two unsafe bare decodes in decodelockers decodelockers in clslockclient.c contains two bare decode operations that allow a malicious or compromised OSD to trigger slab-out-of-bounds reads: 1. cephdecode32p at the...

CVE-2026-52954

A flaw was found in the Linux kernel's libceph component. A remote attacker could send a specially crafted CEPHMSGOSDMAP message containing a corrupted CRUSH map. If this map includes two crushchooseargmaps with identical indices, it triggers an assertion failure, leading to a kernel bug and a...

CVE-2026-52955 libceph: Fix potential out-of-bounds access in crush_decode()

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...

kernel: Linux kernel: Denial of Service in libceph OSD client due to unreset sparse-read state

A flaw was found in the Linux kernel's libceph OSD client. When a connection fault occurs during a sparse read, the sparse-read state is not properly reset. This allows a misbehaving or compromised Ceph OSD server, or a network adversary, to disrupt traffic. As a result, the client can misinterpr...
