CVE-2026-68156

The CVE-2026-68156 issue affects the Linux kernel libceph path: during an authorizer update, ceph_x_update_authorizer() may rebuild the authorizer and, if the new authorizer won’t fit in the existing buffer, it frees the old buffer while auth->authorizer_buf still points to the freed memory. A...

CVE-2026-68153

CVE-2026-68153 (libceph - Linux kernel) : A race during client teardown allows a concurrent read of the monmap debugfs file to access freed memory, causing a use-after-free. The fix drains and removes per-client debugfs files before stopping the OSD/monitor clients, preventing new accesses during...

The vulnerability of the ceph_handle_auth_reply() function in the net/ceph/auth.c module of the Linux operating system allows a hacker to compromise the confidentiality and accessibility of the protected information.

The vulnerability of the cephhandleauthreply function in the net/ceph/auth.c module of the Linux kernel is related to the execution of operations outside of the buffer boundaries. Exploiting this vulnerability could allow a malicious actor to compromise the confidentiality and accessibility of...
