A heap out-of-bounds read security issue exists in the query planning component of MongoDB Server. An authenticated user with database read and write privileges can trigger the security issue through crafted query operations, causing the server to read memory beyond allocated buffer boundaries. The revealed memory contents may be partially observable through diagnostic query statistics output.

CVE-2026-20518 is an out-of-bounds read vulnerability in MediaTek chipsets within the geniezone component. It allows local information disclosure if an attacker has already obtained System privileges and requires user interaction for exploitation. The vulnerability is due to a missing bounds check. A patch is available under Patch IDs ALPS10867524 and ALPS10876355.

This is the official web site of tcpdump, a powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture. Security Fix(es): In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures.(CVE-2026-0799) The rpcap client code that processes a RPCAP_MSG_PACKET message received from the server incorrectly validates its headers. A malicious server can send a crafted message and cause the client to treat up to 20 bytes of the client process memory beyond the end of the buffer as if it was a part of the captured packet.(CVE-2026-18238) rpcapd can allocate up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ message received from the client, but it never frees the memory, so it leaks memory even under normal use. A malicious client can cause the server to leak memory substantially faster.(CVE-2026-18313) libpcap BPF interpreter calls abort() if it encounters a BPF instruction that has an invalid opcode. In particular uncommon use cases a crafted filter program can terminate the OS process.(CVE-2026-31911) libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading the OS process memory in the 32GiB around the buffer on 64-bit architectures and in the entire address space on 32-bit architectures.(CVE-2026-31912) libpcap BPF interpreter for the 'div #k' and 'mod #k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero.(CVE-2026-6244) libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely.(CVE-2026-6554)

CVE-2026-31912 is a medium severity vulnerability in libpcap's BPF interpreter where improper validation of filter program offsets can cause out-of-bounds memory reads. Specifically, the interpreter does not detect reaching the end of the filter buffer without a return instruction or jumps to offsets outside the buffer. This can lead to reading large areas of OS process memory on both 32-bit and 64-bit architectures.

In libxml2 before 2.15.4, xmlFAParsePosCharGroup has an out-of-bounds read, aka an out-of-bounds read in the NXT macro in xmlregexp.

IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote attacker to cause a denial of service due to an out-of-bounds read.

Out-of-bounds read vulnerability in Samsung Opensource rLottie allows Overread Buffers. This issue affects rLottie: 25648aef19187b3f87f4d9420b8d761453ad4630.

There is an out-of-bounds read vulnerability in DASYLab due to improper validation of user-supplied data.   This results in a read a past the end of an allocated heap buffer during string conversion.  Successful exploitation requires an attacker to get a user to open a specially crafted .DSB file.  This issue affects all versions before 2026.0.0.
