CVE-2026-80558

A flaw was found in libceph within the Linux kernel. A remote attacker, by sending a specially crafted or corrupted OSD map osdmap from a Ceph monitor or OSD, could cause the system to attempt to access memory outside of allocated bounds. This out-of-bounds access occurs because invalid OSD indic...

CVE-2026-80557

A flaw was found in the kernel's libceph component. A malicious or compromised Ceph Object Storage Daemon OSD can send a specially crafted message that causes an out-of-bounds read when processing watcher information. This vulnerability can lead to memory corruption or a denial of service,...

CVE-2026-80561

CVE-2026-80561 is a critical (CVSS 9.8) vulnerability in the Linux kernel's libceph component. The decode_locker() function in cls_lock_client.c contains three unsafe decode operations with missing bounds checks, allowing a malicious or compromised OSD in a multi-tenant Ceph deployment to trigger...

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...
