| CVE-2026-3538 | 4 Apple, Google, Linux and 1 more | 4 Macos, Chrome, Linux Kernel and 1 more | 2026-04-18 | 8.8 High |
| Integer overflow in Skia in Google Chrome prior to 145.0.7632.159 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity: Critical) | ||||
| CVE-2026-33899 | 1 Imagemagick | 1 Imagemagick | 2026-04-17 | 5.3 Medium |
| ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-189 and 6.9.13-44, when `Magick` parses an XML file it is possible that a single zero byte is written out of the bounds. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19. | ||||
| CVE-2026-39855 | 2 Mtrojnar, Osslsigncode Project | 2 Osslsigncode, Osslsigncode | 2026-04-17 | 5.5 Medium |
| osslsigncode is a tool that implements Authenticode signing and timestamping. Prior to 2.13, an integer underflow vulnerability exists in osslsigncode version 2.12 and earlier in the PE page-hash computation code (pe_page_hash_calc()). When page hash processing is performed on a PE file, the function subtracts hdrsize from pagesize without first validating that pagesize >= hdrsize. If a malicious PE file sets SizeOfHeaders (hdrsize) larger than SectionAlignment (pagesize), the subtraction underflows and produces a very large unsigned length. The code allocates a zero-filled buffer of pagesize bytes and then attempts to hash pagesize - hdrsize bytes from that buffer. After the underflow, this results in an out-of-bounds read from the heap and can crash the process. The vulnerability can be triggered while signing a malicious PE file with page hashing enabled (-ph), or while verifying a malicious signed PE file that already contains page hashes. Verification of an already signed file does not require the verifier to pass -ph. This vulnerability is fixed in 2.13. | ||||
| CVE-2026-26981 | 2 Academysoftwarefoundation, Openexr | 2 Openexr, Openexr | 2026-04-17 | 6.5 Medium |
| OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.3.0 through 3.3.6 and 3.4.0 through 3.4.4, a heap-buffer-overflow (OOB read) occurs in the `istream_nonparallel_read` function in `ImfContextInit.cpp` when parsing a malformed EXR file through a memory-mapped `IStream`. A signed integer subtraction produces a negative value that is implicitly converted to `size_t`, resulting in a massive length being passed to `memcpy`. Versions 3.3.7 and 3.4.5 contain a patch. | ||||
| CVE-2026-22185 | 1 Openldap | 1 Openldap | 2026-04-16 | 6.8 Medium |
| OpenLDAP Lightning Memory-Mapped Database (LMDB) versions up to and including 0.9.14, prior to commit 8e1fda8, contain a heap buffer underflow in the readline() function of mdb_load. When processing malformed input containing an embedded NUL byte, an unsigned offset calculation can underflow and cause an out-of-bounds read of one byte before the allocated heap buffer. This can cause mdb_load to crash, leading to a limited denial-of-service condition. | ||||
| CVE-2026-20957 | 1 Microsoft | 11 365 Apps, Excel, Excel 2016 and 8 more | 2026-04-16 | 7.8 High |
| Integer underflow (wrap or wraparound) in Microsoft Office Excel allows an unauthorized attacker to execute code locally. | ||||
| CVE-2026-39314 | 1 Openprinting | 1 Cups | 2026-04-16 | 4 Medium |
| OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, an integer underflow vulnerability in _ppdCreateFromIPP() (cups/ppd-cache.c) allows any unprivileged local user to crash the cupsd root process by supplying a negative job-password-supported IPP attribute. The bounds check only caps the upper bound, so a negative value passes validation, is cast to size_t (wrapping to ~2^64), and is used as the length argument to memset() on a 33-byte stack buffer. This causes an immediate SIGSEGV in the cupsd root process. Combined with systemd's Restart=on-failure, an attacker can repeat the crash for sustained denial of service. | ||||
| CVE-2026-27596 | 1 Exiv2 | 1 Exiv2 | 2026-04-16 | 7.5 High |
| Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. The out-of-bounds read is at a 4GB offset, which usually causes Exiv2 to crash. This issue has been patched in version 0.28.8. | ||||
| CVE-2026-23748 | 1 Golioth | 1 Firmware Sdk | 2026-04-16 | 3.7 Low |
| Golioth Firmware SDK version 0.10.0 prior to 0.22.0, fixed in commit d7f55b38, contain an out-of-bounds read in LightDB State string parsing. When processing a string payload, a payload_size value less than 2 can cause a size_t underflow when computing the number of bytes to copy (nbytes). The subsequent memcpy() reads past the end of the network buffer, which can crash the device. The condition is reachable from on_payload, and golioth_payload_is_null() does not block payload_size==1. A malicious server or MITM can trigger a denial of service. | ||||
| CVE-2004-1002 | 2 Canonical, Samba | 2 Ubuntu Linux, Ppp | 2026-04-16 | 7.5 High |
| Integer underflow in pppd in cbcp.c for ppp 2.4.1 allows remote attackers to cause a denial of service (daemon crash) via a CBCP packet with an invalid length value that causes pppd to access an incorrect memory location. | ||||
| CVE-2005-1891 | 2 Aol, Microsoft | 2 Aim, Windows | 2026-04-16 | 7.5 High |
| The GIF parser in ateimg32.dll in AOL Instant Messenger (AIM) 5.9.3797 and earlier allows remote attackers to cause a denial of service (crash) via a malformed buddy icon that causes an integer underflow in a loop counter variable. | ||||
| CVE-2004-0816 | 1 Linux | 1 Linux Kernel | 2026-04-16 | 7.5 High |
| Integer underflow in the firewall logging rules for iptables in Linux before 2.6.8 allows remote attackers to cause a denial of service (application crash) via a malformed IP packet. | ||||
| CVE-2004-0184 | 2 Redhat, Tcpdump | 2 Enterprise Linux, Tcpdump | 2026-04-16 | N/A |
| Integer underflow in the isakmp_id_print for TCPDUMP 3.8.1 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with an Identification payload with a length that becomes less than 8 during byte order conversion, which causes an out-of-bounds read, as demonstrated by the Striker ISAKMP Protocol Test Suite. | ||||
| CVE-2005-0199 | 1 Barton | 1 Ngircd | 2026-04-16 | 9.8 Critical |
| Integer underflow in the Lists_MakeMask() function in lists.c in ngIRCd before 0.8.2 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a long MODE line that causes an incorrect length calculation, which leads to a buffer overflow. | ||||
| CVE-2026-27296 | 2 Adobe, Microsoft | 2 Framemaker, Windows | 2026-04-15 | 7.8 High |
| Adobe Framemaker versions 2022.8 and earlier are affected by an Integer Underflow (Wrap or Wraparound) vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. | ||||
| CVE-2026-27297 | 2 Adobe, Microsoft | 2 Framemaker, Windows | 2026-04-15 | 7.8 High |
| Adobe Framemaker versions 2022.8 and earlier are affected by an Integer Underflow (Wrap or Wraparound) vulnerability that could result in arbitrary code execution in the context of the current user.

| CVE-2025-55118 | 1 Bmc | 1 Control-m/agent | 2026-04-15 | 8.9 High |
| Memory corruptions can be remotely triggered in the Control-M/Agent when SSL/TLS communication is configured. The issue occurs in the following cases: * Control-M/Agent 9.0.20: SSL/TLS configuration is set to the non-default setting "use_openssl=n"; * Control-M/Agent 9.0.21 and 9.0.22: Agent router configuration uses the non-default settings "JAVA_AR=N" and "use_openssl=n" | ||||
| CVE-2025-4948 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-04-15 | 7.5 High |
| A flaw was found in the soup_multipart_new_from_message() function of the libsoup HTTP library, which is commonly used by GNOME and other applications to handle web communications. The issue occurs when the library processes specially crafted multipart messages. Due to improper validation, an internal calculation can go wrong, leading to an integer underflow. This can cause the program to access invalid memory and crash. As a result, any application or server using libsoup could be forced to exit unexpectedly, creating a denial-of-service (DoS) risk. | ||||
