CVE-2026-47276

CVE-2026-47276 affects NanoMQ up to version 0.24.11: a NULL pointer dereference in properties_parse() when processing user_properties, allowing an authenticated attacker to crash the broker by sending a crafted POST to /api/v4/mqtt/publish with user_properties as a JSON array (strlen on a NULL it...

CVE-2026-47276 NULL Pointer Dereference in REST API properties_parse via Malformed user_properties

In nanomq versions 0.24.11 and earlier, a NULL pointer dereference in propertiesparse allows an authenticated attacker to crash the NanoMQ broker by sending a POST request to /api/v4/mqtt/publish with userproperties as a JSON array instead of a JSON object. The crash occurs because strlen is call...

CVE-2026-47275 nanomq NULL Pointer Dereference in MQTTv5 Client CONNECT Decoder Leading to Remote DoS

In nanomq versions 0.24.11 and earlier, a NULL pointer dereference in nnimqttv5msgdecodeconnect allows a malicious MQTT broker to crash any connecting NanoMQ MQTTv5 client including bridge mode with a single packet, causing remote denial of service via SIGSEGV. In nnimqttv5msgdecodeconnect...

CVE-2026-47275

Nanomq has a NULL pointer dereference in nni_mqttv5_msg_decode_connect() (mqtt_codec.c:1863) for versions ≤ 0.24.11. The code iterates CONNECT properties using prop instead of will_prop; when a packet has no connect-level properties but has will properties, dereferencing prop->next can SIGSEGV...

CVE-2026-64187 xfs: fail recovery on a committed log item with no regions

In the Linux kernel, the following vulnerability has been resolved: xfs: fail recovery on a committed log item with no regions If the first op of a transaction is a bare transaction header len == sizeofstruct xfstransheader, xlogrecoveraddtotrans adds an item but no region, leaving it on ritemq...

CVE-2026-64187

CVE-2026-64187 affects the Linux kernel’s XFS log recovery. If the first operation of a transaction is a bare header (len == sizeof(struct xfs_trans_header)) and xlog_recover_add_to_trans() adds an item with no region (ri_buf is NULL), the item can stay on r_itemq with ri_cnt == 0. During recover...

CVE-2026-35590 Possible out-of-bounds read leading to crash when decoding well-crafted EXIF metadata

libvips is a fast image processing library with low memory needs. The EXIF decoder within libvips versions before and including 8.18.1 was not verifying the range of EXIF tag groups before passing data to libexif, leading to a possible null pointer dereference and crash. This has been patched in...

CVE-2026-26199

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If H5Igetname is invoked on a group id with 0 for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if H5Igetname is invoked in a way...

CVE-2026-26199

The CVE-2026-26199 entry describes a buffer underflow in HDF5 when calling H5Iget_name (and H5G_get_name) with a size of zero. Under conditions where an ID is queried with size forced to zero and there is significant data before the name buffer, the function may fail to place a null terminator, l...
