| CVE-2026-50259 | 3 Redhat, X.org, Xorg | 5 Enterprise Linux, X Server, Xorg-server and 2 more | 2026-06-25 | 7.8 High |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-50258 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-06-25 | 7.8 High |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-50256 | 2 Redhat, X.org | 4 Enterprise Linux, X Server, Xorg-server and 1 more | 2026-06-25 | 7.8 High |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| 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-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-2026-12847 | 1 Geovision Inc. | 1 Gv-i O Box 4e | 2026-06-24 | 10 Critical |

| 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-2026-12848 | 1 Geovision Inc. | 1 Gv-i O Box 4e | 2026-06-24 | 10 Critical |

| 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-2026-8356 | 1 The Document Foundation | 1 Libreoffice | 2026-06-16 | 5.5 Medium |
| LibreOffice can import presentations in the legacy binary PPT format. A stack buffer overflow existed when importing a colour-replacement record. Two fixed-size colour tables were filled from the file, but the write position was not reset between the two passes over the record, so a file whose combined colour counts exceeded the table size wrote past the end of the tables on the stack. In fixed versions the unused second pass is no longer read into those tables. | ||||
| CVE-2026-9669 | 1 Python | 1 Cpython | 2026-06-16 | 5.9 Medium |
| bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data. | ||||
| CVE-2026-10829 | 1 Moxa | 2 Nport W2150a-w4 W2250a-w4 Series, Nport W2150a W2250a Series | 2026-06-16 | N/A |
| A stack-based buffer overflow vulnerability has been found in the NPort W2150A-W4/W2250A-W4 Series version 1.5 and earlier. This vulnerability stems from insufficient input validation of user-supplied input in the "Server location" parameter on the Basic settings page. An attacker could exploit this vulnerability by sending crafted input to the web service, resulting in memory corruption. Successful exploitation of this vulnerability could allow remote code execution on the target system with root privileges. | ||||
