| CVE-2026-5856 | 1 Contiki-ng | 1 Contiki-ng | 2026-08-14 | 7.1 High |
| Contiki-NG's DNS/mDNS resolver skip_name() in os/services/resolv/resolv.c walks DNS wire-format name labels with no packet-boundary check, and the caller in newdata() invokes it in a loop iterating nquestions times from the attacker-controlled DNS header before validating the transaction ID. An attacker who sets nquestions higher than the number of complete questions present causes skip_name() to walk past the UDP packet buffer, and the returned pointer is cast to struct dns_answer * for further memory reads. On builds with RESOLV_CONF_SUPPORTS_MDNS enabled, any peer on the local segment can trigger the read unauthenticated via a multicast UDP 5353 packet with no outstanding query required; on standard DNS builds an attacker who can inject a UDP response from port 53 during an outstanding query can trigger the same read. Impact is out-of-bounds read of uip_buf and adjacent memory, disclosing memory contents or crashing the resolver. | ||||
| CVE-2026-5855 | 1 Contiki-ng | 1 Contiki-ng | 2026-08-14 | 7.5 High |
| Contiki-NG's LwM2M TLV parser lwm2m_tlv_read() in os/services/lwm2m/lwm2m-tlv.c ignores its caller-supplied buffer length argument and reads up to six bytes from the input buffer with no bounds check. The caller in lwm2m-engine.c iterates while there is at least one byte remaining, so a crafted CoAP WRITE to any LwM2M endpoint whose final TLV supplies exactly one byte triggers up to five out-of-bounds reads of heap memory adjacent to the CoAP input buffer, disclosing memory contents (including key material and peer addresses) through the parsed tlv->id, tlv->length, and tlv->value fields. Corrupted tlv_len derived from the out-of-bounds memory further corrupts the caller's parse offset. In LwM2M NoSec mode, the default for constrained devices, no authentication is required. | ||||
| CVE-2026-53794 | 2 Rsync Project, Samba | 2 Rsync, Rsync | 2026-08-14 | 5.3 Medium |
| rsync before 3.5.0 contains a logic error in --max-alloc handling that allows a sender or configuration setting --max-alloc=0 to disable allocation sanity checks entirely rather than enforcing a zero-byte cap. Attackers can exploit this flaw to cause the receiver to attempt unbounded memory allocations for file list and data structures, potentially exhausting available memory and causing a denial of service. | ||||
| CVE-2026-53792 | 2 Rsync Project, Samba | 2 Rsync, Rsync | 2026-08-14 | 6.5 Medium |
| rsync before 3.5.0 contains an out-of-bounds read vulnerability in the sender-side block matching logic that allows a malicious receiver to trigger memory access before the start of an allocated buffer by sending a crafted checksum block with a length of zero. Attackers can send a specially crafted checksum set containing a zero-length block to cause a negative offset calculation during delta computation, resulting in an out-of-bounds read of file data buffer memory on the sender side. | ||||
| CVE-2026-43630 | 2 Ggml, Ggml-org | 2 Llama.cpp, Llama.cpp | 2026-08-14 | 6.5 Medium |
| llama.cpp builds b5702 through b7653 contain an out-of-bounds read vulnerability in the recurrent memory state restore path that allows attackers with write access to the slot save directory to read memory past the end of the allocated cells array. Attackers can craft a malicious slot file with an oversized seq_id value to trigger an out-of-bounds read that leaks heap data including pointer values into server logs, defeating ASLR protections and facilitating further exploitation. | ||||
| CVE-2026-43628 | 2 Ggml, Ggml-org | 2 Llama.cpp, Llama.cpp | 2026-08-14 | 7.8 High |
| llama.cpp builds b3978 through b9058 contain an integer underflow and out-of-bounds read vulnerability in the DRY sampler that allows unauthenticated attackers to trigger a heap buffer underflow by sending a crafted HTTP request with dry_allowed_length set to INT32_MIN to the /v1/completions or /v1/chat/completions endpoints. Attackers can exploit this vulnerability to crash the server with SIGSEGV causing denial of service for all connected users, or corrupt token sampling probabilities by reading garbage values from memory before the allocated buffer. | ||||
| CVE-2026-19844 | 1 Totolink | 1 A800r Firmware | 2026-08-14 | 8.8 High |
| A vulnerability was found in TOTOLINK A800R 4.1.2cu.5137_B20200730. The impacted element is the function setRadvdCfg of the file /cgi-bin/cstecgi.cgi of the component ipv6.so. Performing a manipulation of the argument radvdinterfacename results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been made public and could be used. | ||||
