| CVE-2026-54900 | 2026-07-01 | N/A | N/A | ||
| 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 the process. The issue has been fixed in version 3.17.2. | |||||
| CVE-2026-54903 | 2026-07-01 | N/A | N/A | ||
| 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. | |||||
| CVE-2025-62231 | 4 Debian, Ibm, Redhat and 1 more | 11 Debian Linux, Aix, Vios and 8 more | 2026-07-01 | N/A | 7.3 HIGH |
| A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash. | |||||
| CVE-2026-45258 | 1 Freebsd | 1 Freebsd | 2026-07-01 | N/A | 7.8 HIGH |
| 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, either issue allows an unprivileged local user to read and write kernel memory, which can be used to escalate privileges, potentially gaining full control of the affected system. At a minimum, an attacker can crash the kernel, resulting in a Denial of Service (DoS). | |||||
| CVE-2026-49416 | 1 Freebsd | 1 Freebsd | 2026-07-01 | N/A | 7.8 HIGH |
| 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. | |||||
| CVE-2026-58050 | 1 Libssh2 | 1 Libssh2 | 2026-06-30 | N/A | 7.0 HIGH |
| 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. | |||||
| CVE-2025-3360 | 2026-06-30 | N/A | 3.7 LOW | ||
| A flaw was found in GLib. An integer overflow and buffer under-read occur when parsing a long invalid ISO 8601 timestamp with the g_date_time_new_from_iso8601() function. | |||||
| CVE-2025-6035 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-06-30 | N/A | 6.1 MEDIUM |
| A flaw was found in GIMP. An integer overflow vulnerability exists in the GIMP "Despeckle" plug-in. The issue occurs due to unchecked multiplication of image dimensions, such as width, height, and bytes-per-pixel (img_bpp), which can result in allocating insufficient memory and subsequently performing out-of-bounds writes. This issue could lead to heap corruption, a potential denial of service (DoS), or arbitrary code execution in certain scenarios. | |||||
| CVE-2025-5916 | 2 Libarchive, Redhat | 3 Libarchive, Enterprise Linux, Openshift Container Platform | 2026-06-30 | N/A | 3.9 LOW |
| A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive. This bug affects libarchive versions prior to 3.8.0. | |||||
| CVE-2025-5449 | 1 Libssh | 1 Libssh | 2026-06-30 | N/A | 6.5 MEDIUM |
| A flaw was found in the SFTP server message decoding logic of libssh. The issue occurs due to an incorrect packet length check that allows an integer overflow when handling large payload sizes on 32-bit systems. This issue leads to failed memory allocation and causes the server process to crash, resulting in a denial of service. | |||||
| CVE-2025-4945 | 2026-06-30 | N/A | 3.7 LOW | ||
| A flaw was found in the cookie parsing logic of the libsoup HTTP library, used in GNOME applications and other software. The vulnerability arises when processing the expiration date of cookies, where a specially crafted value can trigger an integer overflow. This may result in undefined behavior, allowing an attacker to bypass cookie expiration logic, causing persistent or unintended cookie behavior. The issue stems from improper validation of large integer inputs during date arithmetic operations within the cookie parsing routines. | |||||
| CVE-2025-49179 | 2026-06-30 | N/A | 7.3 HIGH | ||
| A flaw was found in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when computing request length, which allows a client to bypass length checks. | |||||
| CVE-2025-47712 | 2 Nbdkit Project, Redhat | 3 Nbdkit, Enterprise Linux, Enterprise Linux Advanced Virtualization | 2026-06-30 | N/A | 6.5 MEDIUM |
| A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in the nbdkit, leading to a denial of service. | |||||
| CVE-2025-49180 | 2026-06-30 | N/A | 7.8 HIGH | ||
| A flaw was found in the RandR extension, where the RRChangeProviderProperty function does not properly validate input. This issue leads to an integer overflow when computing the total size to allocate. | |||||
| CVE-2025-49176 | 2026-06-30 | N/A | 7.3 HIGH | ||
| A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check. | |||||
| CVE-2025-14242 | 2026-06-30 | N/A | 6.5 MEDIUM | ||
| A flaw was found in vsftpd. This vulnerability allows a denial of service (DoS) via an integer overflow in the ls command parameter parsing, triggered by a remote, authenticated attacker sending a crafted STAT command with a specific byte sequence. | |||||
| CVE-2025-13601 | 2 Gnome, Redhat | 29 Glib, Ceph Storage, Codeready Linux Builder and 26 more | 2026-06-30 | N/A | 7.7 HIGH |
| A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string. | |||||
| CVE-2025-0678 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift Container Platform | 2026-06-30 | N/A | 7.8 HIGH |
| A flaw was found in grub2. When reading data from a squash4 filesystem, grub's squash4 fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the direct_read() will perform a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and may result in arbitrary code execution, by-passing secure boot protections. | |||||
| CVE-2024-45779 | 1 Gnu | 1 Grub2 | 2026-06-29 | N/A | 6.0 MEDIUM |
| An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash. | |||||
| CVE-2024-45778 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift Container Platform | 2026-06-29 | N/A | 4.1 MEDIUM |
| A stack overflow flaw was found when reading a BFS file system. A crafted BFS filesystem may lead to an uncontrolled loop, causing grub2 to crash. | |||||
