| CVE-2026-7838 | UltraVNC viewer through 1.8.2.2 contains an integer overflow leading to a heap buffer overflow in the RFB protocol failure-response parsing path. In vncviewer/ClientConnection.cpp, the 4-byte network-supplied reasonLen field (type CARD32) is passed as reasonLen+1 to CheckBufferSize(). Because both operands are unsigned 32-bit, a reasonLen of 0xFFFFFFFF overflows to 0, causing CheckBufferSize to allocate only 256 bytes. The subsequent ReadString(m_netbuf, reasonLen) call then performs ReadExact f | 8.7 | 無 | 2026-07-01 | 2026-07-01 |
| CVE-2026-7828 | UltraVNC repeater through 1.8.2.2 contains an integer overflow in the HTTP request logging path. In repeater/webgui/settings.c:336, the win_log() function allocates list nodes via malloc(sizeof(struct LIST) + strlen(line)), where line is derived from HTTP request URIs. If strlen(line) is sufficiently large, the addition overflows to a value smaller than sizeof(struct LIST), causing a heap allocation smaller than required. The subsequent strcpy of the full string into the undersized allocation pr | 5.3 | 無 | 2026-07-01 | 2026-07-01 |
| CVE-2026-54903 | Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, Oj.load is vulnerable to heap corruption when parsing a JSON string longer than 2 GB. An integer overflow in buf_append_string (buf.h:61) converts the string length to a large negative size_t, causing memcpy to copy an astronomically large amount of data out of bounds. This crashes the process and can corrupt adjacent heap memory. The issue has been fixed in version 3.17.2. | 6.3 | 無 | 2026-06-30 | 2026-06-30 |
| CVE-2026-54900 | Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, when in usual mode with create_id enabled, Oj::Parser#parse is vulnerable to heap corruption via a negative-size memcpy. When a JSON object key is exactly 65,535 bytes long, an integer truncation in form_attr (usual.c:63) converts the length to -1 before passing it to memcpy. This causes memcpy to copy SIZE_MAX bytes (interpreted as a huge size_t), corrupting heap memory and crashing t | 6.3 | 無 | 2026-06-30 | 2026-06-30 |
| CVE-2026-56363 | ImageMagick before 7.1.2-22 contains a division by zero vulnerability in binomial kernel processing that allows attackers to cause denial of service. An attacker can supply a large binomial kernel value causing integer overflow, resulting in division by zero and application crash. | 4.8 | 無 | 2026-06-30 | 2026-06-30 |
| CVE-2026-53432 | fzf is vulnerable to Integer Overflow leading to crash in FuzzyMatchV2 function. When input line length is approximately 2,200,000 bytes and pattern length is 999 bytes, the product overflows. The Go runtime detects the invalid slice bounds and terminates the process immediately with a non-recoverable panic. This issue was fixed in version 0.73.1. | 5.6 | 無 | 2026-06-30 | 2026-06-30 |
| CVE-2026-57965 | A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation. | 5.1 | 0.12% | 2026-06-29 | 2026-06-29 |
| CVE-2026-58050 | libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation num_attrs * sizeof(libssh2_publickey_attribute) without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious SSH server can then drive the attribute-parsing loop to write past the allocation, causing a heap buffer overflow in a connecting libssh2 client. | 8.3 | 0.31% | 2026-06-27 | 2026-06-30 |
| CVE-2026-49416 | The CONS_HISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of the allocation. An unprivileged local user with access to a vt(4) device can trigger an out-of-bounds write in the kernel, potentially escalating privileges. | 7.8 | 0.15% | 2026-06-27 | 2026-06-30 |
| CVE-2026-45258 | dsp_mmap_single() validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to a buffer address, yielding a mapping that extended past the audio buffer into unrelated kernel memory. The /dev/dsp device nodes are world-accessible by default. On a system with an audio device, | 7.8 | 0.15% | 2026-06-27 | 2026-06-30 |
| CVE-2026-48933 | A flaw in Node.js WebCrypto implementation can crash the process if the input of `subtle.encrypt()` is a multiple of 2GiB. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**. | 7.5 | 1.56% | 2026-06-25 | 2026-06-29 |
| CVE-2026-6679 | A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This affects builds using DTLS 1.3 and wolfSSL version 5.9.0 and earlier. A fix was added to the 5.9.1 release. | 8.8 | 0.39% | 2026-06-25 | 2026-06-27 |
| CVE-2026-54679 | jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvp_string_append has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2. | 6.9 | 0.12% | 2026-06-25 | 2026-06-26 |
| CVE-2026-57235 | Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::NodeSet#[] (and its alias #slice) checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then be used at full width, reading outside the node set's storage. On CRuby this is an out-of-bounds read that typically crashes the process; on JRuby it is not memory-unsafe but returns an incorrect | 6.3 | 0.33% | 2026-06-25 | 2026-06-26 |
| CVE-2026-54226 | A vulnerability in Apache Kvrocks. This issue affects Apache Kvrocks: from 2.6.0 through 2.15.0. Users are recommended to upgrade to version 2.16.0, which fixes the issue. | 6.4 | 0.32% | 2026-06-25 | 2026-06-25 |
| CVE-2026-12244 | If NSD is configured as secondary for a zone, the primary of that zone can crash NSD with an AXFR containing a DNS message with a special crafted SVCB RR with an rdata size of 65512, that let's an (uint16_t) variable that is used to allocate space needed for the RR wrap (because total size > 65535), causing a heap overflow. The attacker can perform a controlled (RCE class) head write of up to 65509 bytes | 8.7 | 0.26% | 2026-06-25 | 2026-06-25 |
| CVE-2026-53059 | In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to region_count overflow The local variable region_count in create_log_context() is declared as unsigned int (32-bit), but dm_sector_div_up() returns sector_t (64-bit). When a device-mapper target has a sufficiently large ti->len with a small region_size, the division result can exceed UINT_MAX. The truncated value is then used to calculate bitset_size, causing clean_bits, sync_bits, and rec | 7.0 | 0.13% | 2026-06-24 | 2026-06-29 |
| CVE-2026-52972 | In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - Cap AEAD AD length to 0x80000000 In order to prevent arithmetic overflows when checking the TX buffer size, cap the associated data length to 0x80000000. | 7.0 | 0.14% | 2026-06-24 | 2026-06-29 |
| CVE-2026-52969 | In the Linux kernel, the following vulnerability has been resolved: KVM: Reject wrapped offset in kvm_reset_dirty_gfn() kvm_reset_dirty_gfn() guards the gfn range with if (!memslot || (offset + __fls(mask)) >= memslot->npages) return; but offset is u64 and the addition is unchecked. The check can be silently bypassed by a u64 wrap. The dirty ring backing those entries is MAP_SHARED at KVM_DIRTY_LOG_PAGE_OFFSET of the vcpu fd, so the VMM can rewrite the slot and offset fields of any entr | 7.0 | 0.15% | 2026-06-24 | 2026-06-29 |
| CVE-2026-48502 | MessagePack for C# is a MessagePack serializer for C#. Prior to 2.5.301 and 3.1.7, MessagePackReader.ReadDateTime() can allocate stack memory based on an attacker-controlled MessagePack extension length. In the slow path for timestamp extension parsing, the computed tokenSize includes the extension body length from the wire and is used in a stackalloc operation before the extension length is validated as one of the valid timestamp sizes. A very small payload can claim a large timestamp extension | 8.2 | 0.26% | 2026-06-22 | 2026-06-23 |
