Wazuh is a free and open source platform used for threat prevention, detection, and response. From 3.9.0 until 4.14.5 and 5.0.0-beta2, the Wazuh cluster protocol in framework/wazuh/core/cluster/common.py allows an authenticated cluster node to exhaust memory on the master. The receivestr method...

libp2p: yamux connection DoS via oversized data frame

SummaryThe yamux stream multiplexer in py-libp2p does not validate incoming DATA frame lengths against the receive window before reading the frame body. Any peer that completes a standard libp2p handshake can send a single 12-byte frame claiming a 4 GB body, causing the victim's yamux read loop t...

CVE-2026-49430

The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...

CVE-2026-49430 Kernel heap overflow in ZFS_IOC_RECV_NEW ioctl

The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...

CVE-2026-49430

The OpenZFS component in FreeBSD contains a kernel memory corruption vulnerability (integer overflow) within the ZFS_IOC_RECV_NEW ioctl in the heal receive path. The issue arises because a 64-bit payload size is truncated to a 32-bit integer for memory allocation, but the original 64-bit size is ...
