CVE-2026-89656: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: libceph: reject buckets with mismatched CRUSH ids crushdecode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from the decoded bucket id. A malformed map can therefore make one bucket...

CVE-2026-80561

A flaw was found in the Linux kernel's libceph component. A malicious or compromised Object Storage Device OSD can exploit multiple unsafe decode operations within the decodelocker function. This can lead to slab-out-of-bounds reads, potentially allowing an attacker to disclose sensitive...

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...
