CVE-2025-49179 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2025-12-11 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.

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-2025-40277 1 Linux 1 Linux Kernel 2025-12-08 7.8 High
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Validate command header size against SVGA_CMD_MAX_DATASIZE This data originates from userspace and is used in buffer offset calculations which could potentially overflow causing an out-of-bounds access.
CVE-2022-50330 1 Linux 1 Linux Kernel 2025-12-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: crypto: cavium - prevent integer overflow loading firmware The "code_length" value comes from the firmware file. If your firmware is untrusted realistically there is probably very little you can do to protect yourself. Still we try to limit the damage as much as possible. Also Smatch marks any data read from the filesystem as untrusted and prints warnings if it not capped correctly. The "ntohl(ucode->code_length) * 2" multiplication can have an integer overflow.
CVE-2021-39254 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2025-12-02 6.7 Medium
A crafted NTFS image can cause an integer overflow in memmove, leading to a heap-based buffer overflow in the function ntfs_attr_record_resize, in NTFS-3G < 2021.8.22.
CVE-2025-0678 2 Gnu, Redhat 4 Grub2, Enterprise Linux, Openshift and 1 more 2025-11-20 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-2025-37984 1 Linux 1 Linux Kernel 2025-11-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: crypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP() Herbert notes that DIV_ROUND_UP() may overflow unnecessarily if an ecdsa implementation's ->key_size() callback returns an unusually large value. Herbert instead suggests (for a division by 8): X / 8 + !!(X & 7) Based on this formula, introduce a generic DIV_ROUND_UP_POW2() macro and use it in lieu of DIV_ROUND_UP() for ->key_size() return values. Additionally, use the macro in ecc_digits_from_bytes(), whose "nbytes" parameter is a ->key_size() return value in some instances, or a user-specified ASN.1 length in the case of ecdsa_get_signature_rs().
CVE-2025-6052 2 Gnome, Redhat 2 Glib, Enterprise Linux 2025-11-07 3.7 Low
A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corruption.
CVE-2025-6196 2 Gnome, Redhat 2 Libgepub, Enterprise Linux 2025-11-06 5.5 Medium
A flaw was found in libgepub, a library used to read EPUB files. The software mishandles file size calculations when opening specially crafted EPUB files, leading to incorrect memory allocations. This issue causes the application to crash. Known affected usage includes desktop services like Tumbler, which may process malicious files automatically when browsing directories. While no direct remote attack vectors are confirmed, any application using libgepub to parse user-supplied EPUB content could be vulnerable to a denial of service.
CVE-2022-0185 3 Linux, Netapp, Redhat 20 Linux Kernel, H300e, H300e Firmware and 17 more 2025-11-06 8.4 High
A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.
CVE-2023-52339 1 Matroska 1 Libebml 2025-11-04 6.5 Medium
In libebml before 1.4.5, an integer overflow in MemIOCallback.cpp can occur when reading or writing. It may result in buffer overflows.
CVE-2025-11463 2 Ashlar, Ashlar Vellum 2 Cobalt, Cobalt 2025-11-04 7.8 High
Ashlar-Vellum Cobalt XE File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of XE files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26626.
CVE-2023-40476 3 Gstreamer, Gstreamer Project, Redhat 3 Gstreamer, Gstreamer, Enterprise Linux 2025-11-04 8.8 High
GStreamer H265 Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of H265 encoded video files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-21768.
CVE-2023-40475 3 Gstreamer, Gstreamer Project, Redhat 3 Gstreamer, Gstreamer, Enterprise Linux 2025-11-04 8.8 High
GStreamer MXF File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of MXF video files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-21661.
CVE-2023-38127 1 Justsystems 19 Easy Postcard Max, Ichitaro 2021, Ichitaro 2022 and 16 more 2025-11-04 7.8 High
An integer overflow exists in the "HyperLinkFrame" stream parser of Ichitaro 2023 1.0.1.59372. A specially crafted document can cause the parser to make an under-sized allocation, which can later allow for memory corruption, potentially resulting in arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2024-23775 1 Arm 1 Mbed Tls 2025-11-04 7.5 High
