——13D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain a buffer overflow vulnerability in the quicksetup.cgi interface. A remote attacker can write overly long strings to the test4, ssid2, and username fields and execute arbitrary commands by crafting a specific payload, or cause the device to crash.1dCVE-2026-719579.8 CRI45.2%
——14D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain a buffer overflow vulnerability in the app.cgi interface. A remote attacker can write an overly long string to the netAcc.addlist[].name field and execute arbitrary commands by crafting a specific payload, or cause the device to crash.3dCVE-2026-203487.5 HIG25.3%
——8A vulnerability in the XAR file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition or possibly other expanded impacts as a result of memory corruption on an affected device.
This vulnerability is due to improper boundary checks for content in XAR files during scanning. An attacker could exploit this vulnerability by submitting a crafted file that contains XAR content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.4dCVE-2026-203377.5 HIG28.9%
——9A vulnerability in the zip archive parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition on an affected device.
This vulnerability is due to improper boundary checks for content in zip files during scanning, which may result in an out-of-bounds write condition. An attacker could exploit this vulnerability by submitting a crafted zip file for scanning. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.4dCVE-2026-678717.5 HIG38.0%
