| CVE-2026-5089 | 2026-10-26 | N/A | 7.3 HIGH | ||
| YAML::Syck versions before 1.38 for Perl has an out-of-bounds read. The base60 (sexagesimal) parsing code in perl_syck.h has a buffer underflow bug in both int#base60 and float#base60 handlers. When processing the leftmost segment of a colon-separated value (e.g., the 1 in 1:30:45), the inner while loop can decrement a pointer past the start of the string buffer: while ( colon >= ptr && *colon != ':' ) { colon--; } if ( *colon == ':' ) *colon = '\0'; // colon may be ptr-1 here When no colon is found (final/leftmost segment), colon becomes ptr-1, and the subsequent *colon dereference reads one byte before the allocated buffer. | |||||
| CVE-2026-26199 | 1 Hdfgroup | 1 Hdf5 | 2026-10-24 | N/A | 6.5 MEDIUM |
| HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If `H5Iget_name` is invoked on a group id with `0` for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if `H5Iget_name` is invoked in a way where `size` can be forced to zero, and there is important data before the `name` buffer. | |||||
| CVE-2026-16439 | 1 Eclipse | 1 Openj9 | 2026-10-24 | N/A | 9.1 CRITICAL |
| In Eclipse OpenJ9 versions up to 0.60, using -Xtrace to trace method arguments can lead to buffer underflow. | |||||
| CVE-2026-71969 | 2026-10-24 | N/A | 6.7 MEDIUM | ||
| OP-TEE OS through 4.10.0, fixed in commit 7b8b494, contains a buffer underwrite vulnerability in the RSA NOPAD encrypt and decrypt operations within the mbedTLS software backend and SE050 hardware driver that allows a malicious Trusted Application to corrupt secure-world heap memory by supplying an input length exceeding the RSA modulus size. When src_len exceeds rsa_len, the subtraction expression wraps to a large unsigned value, causing a subsequent memcpy to write attacker-controlled data before the destination buffer in S-EL1 secure-world heap memory. | |||||
| CVE-2026-34253 | 2026-10-19 | N/A | 8.2 HIGH | ||
| A buffer underflow vulnerability has been identified in the ogg123 utility from the vorbis-tools 1.4.3 package in function remotethread in remote.c. This vulnerability occurs in the remote control functionality when processing malformed input, leading to a stack buffer underflow that can cause application crashes and potentially allow code execution. | |||||
| CVE-2025-62786 | 1 Wazuh | 1 Wazuh | 2026-10-19 | N/A | 8.1 HIGH |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. A heap-based out-of-bounds WRITE occurs in decode_win_permissions, resulting in writing a NULL byte 2 bytes before the start of the buffer allocated to decoded_it. A compromised agent can potentially leverage this issue to perform remote code execution, by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially achieve remote code execution on the wazuh manager (the exploitability of this vulnerability depends on the specifics of the respective heap allocator). This vulnerability is fixed in 4.10.2. | |||||
| CVE-2026-109448 | 2026-10-16 | N/A | 5.9 MEDIUM | ||
| Integer wraparound in psqlODBC SQLBindParameter allows an application, or an attacker who controls how many parameters the application binds on one statement, to corrupt heap memory. psqlODBC stores the binding count in a signed 16-bit field. Binding parameter number 32768 wraps that count to -32768. Binding parameter 32769 then writes about 2.5 MB of zeros starting 1.25 MB before the binding array, which crashes the application or leaves it running on a corrupted heap. Applications that build parameter lists from untrusted input, such as an IN (?, ?, ...) list, are exposed. Versions before psqlODBC 18.00.0005 are affected. | |||||
| CVE-2026-97008 | 1 Microsoft | 5 365 Apps, Microsoft 365, Office 2021 and 2 more | 2026-10-15 | N/A | 8.8 HIGH |
| Buffer underwrite ('buffer underflow') in Microsoft Office Excel allows an unauthorized attacker to execute code over a network. | |||||
| CVE-2026-16179 | 1 Ibm | 1 Datapower Gateway | 2026-10-15 | N/A | 7.5 HIGH |
| IBM DataPower Gateway 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 could allow an attacker to cause a heap buffer underwrite and potentially crash the service. | |||||
| CVE-2026-109964 | 2026-10-13 | N/A | 5.6 MEDIUM | ||
| ImageMagick before 7.1.2-33 and 6.9.13-58 contains a heap buffer underwrite vulnerability in DecodeImage() in coders/pict.c on 32-bit builds due to pointer arithmetic overflow. Attackers can supply a crafted PICT file with maximized row, column and bytes-per-line values to bypass bounds checks and write up to 128 controlled bytes below the heap buffer, causing crashes or code execution. | |||||
| CVE-2025-68114 | 1 Capstone-engine | 1 Capstone | 2026-10-13 | N/A | 4.8 MEDIUM |
| Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue. | |||||
| CVE-2025-61690 | 2026-10-12 | N/A | 7.8 HIGH | ||
| KV STUDIO versions 12.23 and prior contain a buffer underflow vulnerability. If the product uses a specially crafted file, arbitrary code may be executed on the affected product. | |||||
| CVE-2025-61915 | 2 Opengroup, Openprinting | 2 Unix, Cups | 2026-10-07 | N/A | 6.0 MEDIUM |
| OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.15, a user in the lpadmin group can use the cups web ui to change the config and insert a malicious line. Then the cupsd process which runs as root will parse the new config and cause an out-of-bound write. This issue has been patched in version 2.4.15. | |||||
| CVE-2026-73075 | 1 Vim | 1 Vim | 2026-10-06 | N/A | 3.9 LOW |
| Vim is an open source, command line text editor. From 9.2.0469 until 9.2.0843, popup_mark_opacity_zindex() in src/popupwin.c can use a negative w_winrow for a text-property-anchored popup with clipwindow and opacity, indexing before the screen array instead of accounting for w_popup_topoff and causing an out-of-bounds read and conditional write. This issue is fixed in version 9.2.0843. | |||||
| CVE-2026-20104 | 1 Cisco | 1 Ios Xe | 2026-09-28 | N/A | 6.1 MEDIUM |
| A vulnerability in the bootloader of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches, Cisco Catalyst ESS9300 Embedded Series Switches, Cisco Catalyst IE9310 and IE9320 Rugged Series Switches, and Cisco IE3500 and IE3505 Rugged Series Switches could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to an affected device to execute arbitrary code at boot time and break the chain of trust. This vulnerability is due to insufficient validation of software at boot time. An attacker could exploit this vulnerability by manipulating the loaded binaries on an affected device to bypass some of the integrity checks that are performed during the boot process. A successful exploit could allow the attacker to execute code that bypasses the requirement to run Cisco-signed images. Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates because this vulnerability allows an attacker to bypass a major security feature of a device. | |||||
| CVE-2025-4373 | 2026-09-21 | N/A | 4.8 MEDIUM | ||
| A flaw was found in GLib, which is vulnerable to an integer overflow in the g_string_insert_unichar() function. When the position at which to insert the character is large, the position will overflow, leading to a buffer underwrite. | |||||
| CVE-2026-40013 | 2026-09-03 | N/A | 4.3 MEDIUM | ||
| An attacker that has valid credentials can submit a Sieve script containing an extreme numeric literal, which causes an out-of-bounds write when the ManageSieve service compiles the script. This causes memory corruption and an observed crash of the ManageSieve process, resulting in denial of service for script management. This might be able to be used for remote code execution. Disable the ManageSieve service if users do not need remote Sieve script management. Update to non-vulnerable version. No publicly available exploits are known. | |||||
| CVE-2026-0966 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | N/A | 8.2 HIGH |
| A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process. | |||||
| CVE-2024-36343 | 2026-07-24 | N/A | N/A | ||
