An incorrect buffer size calculation in the epoch key generator in OpenVPN ovpn-dco-win version 2.0.0 through 2.8.3 allows a remote authenticated peer to trigger a heap-based buffer overflow and kernel memory corruption via a crafted data packet, resulting in a system crash (denial of service).

CVE-2026-54715——
———GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through the browser. In version 1.10.2, parse_browser assumes the matched browser token begins with Opera and moves a trailing version substring to match plus five, allowing a crafted User-Agent in a processed access log to write one to four attacker-influenced bytes beyond the heap allocation and corrupt or crash GoAccess. This issue is fixed in version 1.11.6hCVE-2026-512729.8 CRI—
———In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the latinToUTF8() character encoding conversion function. The function calculates required buffer size by simply doubling input length and reallocates ps_ptr heap buffer without strict boundary validation. Malicious oversized input can trigger insufficient buffer allocation and out-of-bounds write during Latin-1 to UTF-8 conversion, leading to code execution, information disclosure, denial of service or privilege escalation.7hCVE-2026-11771——
———OpenVPN version 2.1.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows attackers via an off-by-one buffer write in the NTLM proxy authentication to potentially cause a crash via a crafted NTLM response from a malicious proxy server8hCVE-2026-478769.3 CRI—
———VMware ESX contains an out-of-bounds write vulnerability in the VMXNET3 virtual network adapter. A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host. Non VMXNET3 virtual adapters are not affected by this issue.13hCVE-2026-17544——
———Attacker-provided inputs to bccomp() could lead to an out-of-bounds write with stack and heap corruption in PHP versions from 8.4.* before 8.4.24 and from 8.5.* before 8.5.9.11hCVE-2026-179518.8 HIG—
——0Heap buffer overflow in WebRTC in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: Low)11h
