CVE-2025-12464 1 Redhat 3 Enterprise Linux, Openshift, Rhivos 2026-06-25 6.2 Medium
A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This could lead to a buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user could use this vulnerability to crash the QEMU process on the host, resulting in a denial of service.
CVE-2025-48796 1 Redhat 2 Enterprise Linux, Rhivos 2026-06-25 7.3 High
A flaw was found in GIMP. The GIMP ani_load_image() function is vulnerable to a stack-based overflow. If a user opens.ANI files, GIMP may be used to store more information than the capacity allows. This flaw allows a malicious ANI file to trigger arbitrary code execution.
CVE-2025-26595 3 Redhat, Tigervnc, X.org 10 Enterprise Linux, Rhel Aus, Rhel E4s and 7 more 2026-06-25 7.8 High
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.
CVE-2026-51844 1 Tenda 1 Ac7 2026-06-24 9.8 Critical
Tenda AC7 v15.03.06.44 contains a stack buffer overflow vulnerability in the /goform/AdvSetMacMtuWan interface via the cloneType parameter.
CVE-2026-12485 1 Geovision Inc. 2 Gv-i/o Box 4e, Gv-i O Box 4e 2026-06-24 10 Critical
GV-I/O Box 4E is a smart embedded device with 4 input and 4 relays output that can be controlled over Ethernet and RS-485. DVRSearch is a service running by default on the IOBox listening for UDP messages on port 10001. Any user on the network can send messages to this service and interact with it. Upon receiving a UDP message, the server reads at most 1460 bytes into a local buffer and a pointer to the buffer is stored in a global variable: #### IP field stack overflow The following code is vulnerable to a stack overflow that is attacker-controlled: v3 = strlen(g_network_config->ip_addr); memcpy(&reply_buf[36], g_network_config->ip_addr, v3);

CVE-2026-12488 1 Geovision Inc. 1 Geovision 2026-06-24 6.2 Medium
A memory corruption vulnerability exists in the GV-Cloud functionality of GeoVision GV-VMS V20 20.0.2.  A specially crafted network request can lead to a denial of service. An attacker can impersonate the legitimate server to trigger this vulnerability.

CVE-2026-44089 1 Totolink 1 Ex1200l 2026-06-23 N/A
Totolink EX1200L router is vulnerable to Buffer Overflow in the login functionality in cgi-bin/cstecgi.cgi endpoint. This vulnerability could be exploited to cause the program to crash and to execute code remotely. This allows the attacker to perform actions as root including reading and editing data, as well as bricking the router. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 9.3.5u.6146_B20201023 but may also affect other versions.
CVE-2026-51845 1 Tenda 1 Ac7 2026-06-22 9.8 Critical
Tenda AC7 v15.03.06.44 contains a stack buffer overflow vulnerability in the /goform/AdvSetMacMtuWan interface via the mac parameter.
CVE-2026-51846 1 Tenda 1 Ac7 2026-06-22 9.8 Critical
In Tenda AC7 v15.03.06.44, the wanSpeed parameter of the route /goform/AdvSetMacMtuWan has a stack buffer overflow vulnerability that can lead to remote arbitrary code execution.
CVE-2026-51843 1 Tenda 1 Ac7 2026-06-22 9.8 Critical
Tenda AC7 v15.03.06.44 contains a stack buffer overflow vulnerability in the /goform/AdvSetMacMtuWan interface via the wanMTU parameter.
CVE-2026-48715 1 Radvd-project 1 Radvdump 2026-06-22 N/A
radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the `radvdump` utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, `print_ff()` copies up to 2032 bytes from attacker-controlled packet data into a 16-byte `struct in6_addr` on the stack, overflowing by up to 2016 bytes. Note that the main `radvd` daemon is not affected by the vulnerability. Version 2.21 patches the issue.
CVE-2025-55660 1 Gpac 1 Mp4box 2026-06-19 5.5 Medium
A stack overflow in the gf_opus_read_length function (media_tools/av_parsers.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
CVE-2026-7273 1 Zyxel 10 Gs1900-10hp Firmware, Gs1900-16 Firmware, Gs1900-24 Firmware and 7 more 2026-06-18 8.8 High
A stack-based buffer overflow vulnerability in the CGI program of Zyxel GS1900-48HPv2 firmware versions through 2.90(ABTQ.1)C0 could allow a LAN-based, unauthenticated attacker to exploit the flaw and potentially execute OS commands via a crafted HTTP request.
CVE-2026-55738 1 Rxi 1 Microtar 2026-06-17 8.8 High
A stack-based buffer overflow exists in the raw_to_header() function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy() without guaranteeing null termination of the source. The POSIX ustar format permits these fixed-width fields to be fully populated with non-null bytes, so a crafted archive whose linkname field (followed by the trailing padding of the 512-byte raw header) contains no null terminator causes strcpy() to read past the end of the 512-byte raw header stack buffer and to write past the destination header buffer. A remote attacker who supplies a crafted TAR archive that the victim opens or parses (via mtar_open(), mtar_read_header(), or mtar_find()) can cause an out-of-bounds read and a stack buffer overflow, resulting in denial of service (crash) and potentially arbitrary code execution. Confirmed with AddressSanitizer: stack-buffer-overflow READ of size 356 in raw_to_header at src/microtar.c:112.
