kernel: Linux kernel: Denial of Service in libceph OSD client due to unreset sparse-read state

A flaw was found in the Linux kernel's libceph OSD client. When a connection fault occurs during a sparse read, the sparse-read state is not properly reset. This allows a misbehaving or compromised Ceph OSD server, or a network adversary, to disrupt traffic. As a result, the client can misinterpr...
