About this tag
The ceph tag on WindowsForum.com covers discussions about the Ceph distributed storage system, particularly its Linux kernel client implementation. Recent threads focus on security vulnerabilities and bug fixes in the Ceph client code, including CVE-2026-22990 which replaced a BUG_ON assertion with a safe error path in osdmap_apply_incremental(), and CVE-2026-22992 which fixed an authentication state mismatch in libceph that could lead to kernel NULL-pointer dereferences. These topics are relevant for system administrators and storage engineers managing Ceph clusters, especially those concerned with kernel stability, security patching, and defensive coding practices. The tag content emphasizes operational impacts and mitigation strategies for Ceph deployments.

  1. Linux Kernel Ceph Client Patch Replaces BUG_ON with Safe Error Path CVE-2026-22990

    A small change in the Linux kernel’s Ceph client code — replacing a fatal assertion with a graceful error path in osdmap_apply_incremental() — closed CVE‑2026‑22990, eliminating a trivial path to a kernel panic but raising a set of operational and defensive‑coding questions operators should not...

  2. CVE-2026-22992: Kernel libceph Fix Prevents Auth State Mismatch in Ceph

    The Linux kernel received a small but consequential bugfix in the Ceph client library (libceph) that corrects a missing error return in the authentication completion path — a change tracked as CVE‑2026‑22992 that, if left unpatched, can leave higher layers confused about authentication state and...
