CVE-2026-80558

This Linux kernel vulnerability affects the libceph subsystem. A corrupted osdmap received from a Ceph monitor or OSD may contain OSD indices in its primary_temp field that are greater than max_osd or smaller than CEPH_HOMELESS_OSD (-1). While most OSD indices in the osdmap are validated, the one...

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...

CVE-2026-68158

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix multiplication overflow in decodenewupstateweight If a message of type CEPHMSGOSDMAP contains a maliciously corrupted osdmap, out-of-bounds memory accesses may occur in decodenewupstateweight.
