| CVE-2026-65704 | 1 Ffmpeg | 1 Ffmpeg | 2026-07-28 | 7.8 High |
| FFmpeg through 8.1.2 contains an out-of-bounds write vulnerability that allows attackers to cause heap corruption by supplying a crafted ffconcat file processed with the -safe 0 flag. The TY demuxer's demux_audio() function decrements packet size without bounds checking, producing a negative size value that is passed to memcpy() in shorten_decode_frame(), where conversion to size_t wraps the value to near SIZE_MAX and triggers reads beyond the source allocation and writes far beyond the Shorten decoder's bitstream buffer. | ||||
| CVE-2026-48029 | 1 Struktur | 1 Libheif | 2026-07-27 | 7.1 High |
| libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.19.0 through 1.21.2 have a heap OOB read in ImageItem_Grid::decode_grid_tile via irot-induced tile-coordinate underflow. Version 1.22.0 fixes the issue. | ||||
| CVE-2026-45813 | 1 Apache | 1 Nimble | 2026-07-24 | 8.8 High |
| Out-of-bounds Write, Integer Underflow (Wrap or Wraparound) vulnerability in Apache NimBLE BASS service. Improper validation when parsing BASS service "Add Source" and "Modify Source" operation PDU could results in stack buffer overflow or arbitrary out-of-bound read. This can be triggered by nearby devices over Bluetooth connection, however pairing is required prior to accessing BASS service, which depending on device configuration may or may not require user action. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue. | ||||
| CVE-2026-63868 | 1 Linux | 1 Linux Kernel | 2026-07-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: garp: fix unsigned integer underflow in garp_pdu_parse_attr The receive-side GARP attribute parser computes dlen with reversed operands: dlen = sizeof(*ga) - ga->len; ga->len is the on-wire attribute length and includes the GARP attribute header. For normal attributes with data, ga->len is larger than sizeof(*ga), so the subtraction underflows in unsigned arithmetic. The resulting value is later passed to garp_attr_lookup(), whose length argument is u8. After truncation, the parsed data length usually no longer matches the length stored for locally registered attributes, so received Join/Leave events are ignored. This breaks the GARP receive path for common attributes, such as GVRP VLAN registration attributes. Compute the data length as the attribute length minus the header length. | ||||
| CVE-2026-33845 | 2 Gnu, Redhat | 16 Gnutls, Ai Inference Server, Discovery and 13 more | 2026-07-20 | 7.5 High |
| A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service. | ||||
| CVE-2026-44251 | 1 Wazuh | 1 Wazuh | 2026-07-17 | 6.5 Medium |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.0.0 and above, prior to 4.14.5, a size_t integer underflow in os_crypto/shared/msgs.c:389 allows any enrolled Wazuh agent to crash the wazuh-remoted process on the manager, immediately disconnecting all agents from the manager. A second code path reached by the same underflow may allow heap memory corruption. This issue has been fixed in version 4.14.5. | ||||

| CVE-2026-29008 | 2 Denx, U-boot | 2 U-boot, U-boot | 2026-07-14 | 7.5 High |
| U-Boot through 2026.04-rc3 contains an integer underflow vulnerability in the tcp_rx_state_machine() function (net/tcp.c) that allows a network-adjacent attacker to crash the bootloader by sending a malformed TCP SYN+ACK packet with a manipulated data offset field causing payload_len to become negative. When the TCP_SYN_SENT handler calls tcp_rx_user_data() without invoking tcp_seg_in_wnd() validation, the negative payload_len is implicitly converted to a large unsigned integer (e.g., 0xFFFFFFD8) and passed to memcpy() in store_block(), causing an immediate crash that prevents device boot and may enable memory corruption when CONFIG_LMB is disabled. | ||||
| CVE-2026-55011 | 1 Microsoft | 1 Malware Protection Engine | 2026-07-14 | 7.8 High |
| Integer underflow (wrap or wraparound) in Microsoft Defender allows an unauthorized attacker to execute code locally. | ||||
| CVE-2026-50308 | 1 Microsoft | 13 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 10 more | 2026-07-14 | 7.8 High |
| Integer underflow (wrap or wraparound) in Windows NTFS allows an unauthorized attacker to execute code locally. | ||||
| CVE-2026-25075 | 1 Strongswan | 1 Strongswan | 2026-07-14 | 7.5 High |
| strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication. Attackers can exploit the failure to validate AVP length fields before subtraction to trigger excessive memory allocation or NULL pointer dereference, crashing the charon IKE daemon. | ||||
| CVE-2026-45463 | 1 Microsoft | 9 365 Apps, Office, Office 2016 and 6 more | 2026-07-08 | 8.4 High |
| Integer underflow (wrap or wraparound) in Microsoft Office allows an unauthorized attacker to execute code locally. | ||||
| CVE-2026-55490 | 1 Openwrt | 1 Openwrt | 2026-07-08 | 6.5 Medium |
| OpenWrt is a Linux operating system targeting embedded devices. Before v25.12.5, an integer underflow in handle_send_a() of the Emergency Access Daemon allows any unauthenticated attacker on the local network to crash the daemon by sending a single crafted UDP packet. The message length underflows before a bounds check and is then passed to memcpy as a very large size. This issue is fixed v25.12.5. | ||||
| CVE-2025-4948 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-06-30 | 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. | ||||
| CVE-2026-58058 | 1 Nmap | 1 Nmap | 2026-06-29 | 6.5 Medium |
| Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6_get_data_primitive (libnetutil/netutil.cc), so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a crafted IPv6 response with a truncated extension header can trigger out-of-bounds reads and a crash during raw IPv6 scans. | ||||
