Copyright © 2012 Red Hat, Inc. All rights reserved. Moderate 2026-05-06T00:00:00 kernel: ceph: supply snapshot context in ceph_zero_partial_object() 7.0 CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H CWE-372

A flaw was found in the Linux kernel's Ceph file system module. The `ceph_zero_partial_object` function, responsible for handling object write operations, was missing proper snapshot context. This oversight could allow a local attacker to cause data inconsistencies within snapshots, leading to a loss of data integrity for previously snapshotted data.

Red Hat acknowledges the upstream Linux kernel correction for «ceph» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration. To mitigate this issue, prevent the ceph module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
