CVE-2026-5856

Contiki-NG's DNS/mDNS resolver skipname 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 attack...

CVE-2026-5855 Contiki-NG LwM2M TLV Parser Out-of-Bounds Read via Unchecked Buffer Length in lwm2m_tlv_read

Contiki-NG's LwM2M TLV parser lwm2mtlvread 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...

CVE-2026-5855

Contiki-NG: LwM2M TLV parser in os/services/lwm2m/lwm2m-tlv.c (function lwm2m_tlv_read) ignores the caller’s buffer length and may read up to six bytes without bounds checks. The engine loop continues while bytes remain, so a crafted CoAP WRITE to any LwM2M endpoint whose final TLV supplies exact...

CVE-2026-70634 TimescaleDB 2.29.1 Out-of-Bounds Read Information Disclosure via Dictionary Compression Reverse Iterator

TimescaleDB through 2.29.1, fixed in commit 517c13e, contains an out-of-bounds read in the Dictionary compression reverse row iterator tsl/src/compression/algorithms/dictionary.c. The forward path validates the decoded index; the reverse path uses an assertion compiled out of release builds,...

CVE-2026-70634

TimescaleDB 2.29.1 contains an out-of-bounds read in the Dictionary compression reverse row iterator (tsl/src/compression/algorithms/dictionary.c). The reverse path does not validate the 64-bit Simple8b index (an assertion is compiled out in release builds); attackers with DML access to a physica...

CVE-2026-43630

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 a...

kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()

A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...

CVE-2026-64571

A flaw was found in the Linux kernel's wifi: p54 component. A local attacker with a malicious USB device could exploit this by sending a specially crafted frame during an EEPROM Electrically Erasable Programmable Read-Only Memory readback operation. This vulnerability allows the device to read...

AZL-94496 CVE-2026-19027 affecting package hdf5 1.14.6-4

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 prior to 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap...

CVE-2026-71498: Out-of-bounds Read

node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated incomplete multi-byte UTF-8 sequence could cause the native binding to read past the end of the allocated buffer while attempting to decode the final,...

PT-2026-68968

Summary re2 infers a character's byte length from its UTF-8 lead byte alone, with no bound on the bytes actually remaining in the input. Buffer arguments reach the native layer verbatim — only strings are re-encoded into well-formed UTF-8 — so a Buffer whose last byte is a multi-byte lead promise...
