CVE-2021-22301 1 Huawei 2 Mate 30, Mate 30 Firmware 2026-06-17 4.6 MEDIUM 6.7 MEDIUM
Mate 30 10.0.0.203(C00E201R7P2) have a buffer overflow vulnerability. After obtaining the root permission, an attacker can exploit the vulnerability to cause buffer overflow.
CVE-2021-22275 1 Br-automation 1 Automation Runtime 2026-06-17 7.8 HIGH 8.6 HIGH
Buffer Overflow vulnerability in B&R Automation Runtime webserver allows an unauthenticated network-based attacker to stop the cyclic program on the device and cause a denial of service.
CVE-2021-22129 1 Fortinet 1 Fortimail 2026-06-17 6.5 MEDIUM 8.8 HIGH
Multiple instances of incorrect calculation of buffer size in the Webmail and Administrative interface of FortiMail before 6.4.5 may allow an authenticated attacker with regular webmail access to trigger a buffer overflow and to possibly execute unauthorized code or commands via specifically crafted HTTP requests.
CVE-2021-21970 1 Sealevel 2 Seaconnect 370w, Seaconnect 370w Firmware 2026-06-17 6.8 MEDIUM 8.1 HIGH
An out-of-bounds write vulnerability exists in the HandleSeaCloudMessage functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. The HandleIncomingSeaCloudMessage function uses at [3] the json_object_get_string to populate the p_name global variable. The p_name is only 0x80 bytes long, and the total MQTT message could be up to 0x201 bytes. Because the function json_object_get_string will fill str based on the length of the json’s value and not the actual str size, this would result in a possible out-of-bounds write.
CVE-2021-21969 1 Sealevel 2 Seaconnect 370w, Seaconnect 370w Firmware 2026-06-17 6.8 MEDIUM 8.1 HIGH
An out-of-bounds write vulnerability exists in the HandleSeaCloudMessage functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. The HandleIncomingSeaCloudMessage function uses at [4] the json_object_get_string to populate the p_payload global variable. The p_payload is only 0x100 bytes long, and the total MQTT message could be up to 0x201 bytes. Because the function json_object_get_string will fill str based on the length of the json’s value and not the actual str size, this would result in a possible out-of-bounds write.
CVE-2021-21967 1 Sealevel 2 Seaconnect 370w, Seaconnect 370w Firmware 2026-06-17 7.1 HIGH 5.9 MEDIUM
An out-of-bounds write vulnerability exists in the OTA update task functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted MQTT payload can lead to denial of service. An attacker can perform a man-in-the-middle attack to trigger this vulnerability.
CVE-2021-21939 1 Accusoft 1 Imagegear 2026-06-17 6.8 MEDIUM 8.8 HIGH
A heap-based buffer overflow vulnerability exists in the XWD parser functionality of Accusoft ImageGear 19.10. A specially-crafted file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-21903 1 Garrett 1 Ic Module Cma 2026-06-17 10.0 HIGH 9.8 CRITICAL
A stack-based buffer overflow vulnerability exists in the CMA check_udp_crc function of Garrett Metal Detectors’ iC Module CMA Version 5.0. A specially-crafted packet can lead to a stack-based buffer overflow during a call to strcpy. An attacker can send a malicious packet to trigger this vulnerability.
CVE-2021-21901 1 Garrett 1 Ic Module Cma 2026-06-17 9.0 HIGH 8.8 HIGH
A stack-based buffer overflow vulnerability exists in the CMA check_udp_crc function of Garrett Metal Detectors’ iC Module CMA Version 5.0. A specially-crafted packet can lead to a stack-based buffer overflow during a call to memcpy. An attacker can send a malicious packet to trigger this vulnerability.
CVE-2021-21828 1 Att 1 Xmill 2026-06-17 7.5 HIGH 9.8 CRITICAL
A heap-based buffer overflow vulnerability exists in the XML Decompression DecodeTreeBlock functionality of AT&T Labs Xmill 0.7. In the default case of DecodeTreeBlock a label is created via CurPath::AddLabel in order to track the label for later reference. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-21827 1 Att 1 Xmill 2026-06-17 7.5 HIGH 9.8 CRITICAL
A heap-based buffer overflow vulnerability exists in the XML Decompression DecodeTreeBlock functionality of AT&T Labs Xmill 0.7. Within `DecodeTreeBlock` which is called during the decompression of an XMI file, a UINT32 is loaded from the file and used as trusted input as the length of a buffer. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-21826 1 Att 1 Xmill 2026-06-17 7.5 HIGH 9.8 CRITICAL
A heap-based buffer overflow vulnerability exists in the XML Decompression DecodeTreeBlock functionality of AT&T Labs Xmill 0.7. Within `DecodeTreeBlock` which is called during the decompression of an XMI file, a UINT32 is loaded from the file and used as trusted input as the length of a buffer. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-21808 1 Accusoft 1 Imagegear 2026-06-17 6.8 MEDIUM 8.8 HIGH
A memory corruption vulnerability exists in the PNG png_palette_process functionality of Accusoft ImageGear 19.9. A specially crafted malformed file can lead to a heap buffer overflow. An attacker can provide malicious inputs to trigger this vulnerability.
CVE-2021-21282 1 Contiki-ng 1 Contiki-ng 2026-06-17 7.5 HIGH 8.6 HIGH
Contiki-NG is an open-source, cross-platform operating system for internet of things devices. In versions prior to 4.5, buffer overflow can be triggered by an input packet when using either of Contiki-NG's two RPL implementations in source-routing mode. The problem has been patched in Contiki-NG 4.5. Users can apply the patch for this vulnerability out-of-band as a workaround.
CVE-2021-21281 1 Contiki-ng 1 Contiki-ng 2026-06-17 7.5 HIGH 7.0 HIGH
Contiki-NG is an open-source, cross-platform operating system for internet of things devices. A buffer overflow vulnerability exists in Contiki-NG versions prior to 4.6. After establishing a TCP socket using the tcp-socket library, it is possible for the remote end to send a packet with a data offset that is unvalidated. The problem has been patched in Contiki-NG 4.6. Users can apply the patch for this vulnerability out-of-band as a workaround.
