CVE-2026-81581 Aug 27, 07:46 HIGH PATCH This Week

WibuKey64.sys kernel-mode driver in Wibu-Systems WibuKey up to version 6.70 for Windows allows a local, low-privileged attacker to trigger memory boundary violations by supplying out-of-scope pointer values, with outcomes ranging from denial of service (BSOD) to full SYSTEM-level privilege escalation via kernel code execution. The CVSS Scope:Changed metric reflects the critical boundary crossing from user-space into the driver's SYSTEM-privileged kernel context, meaning successful exploitation yields complete machine control from an unprivileged account. No public exploit has been identified at time of analysis and WibuKey has not been listed in the CISA KEV catalog, but the low attack complexity makes this a high-value local privilege escalation primitive for post-compromise chains.

CVE-2026-81579 Aug 27, 07:42 HIGH PATCH This Week

Local privilege escalation in WibuKey for Windows before 6.71 allows any low-privileged local user to gain full SYSTEM-level control by exploiting a write-what-where primitive in the WibuKey2_64.sys kernel driver. The root cause is an untrusted pointer dereference (CWE-123) in the 64-bit kernel driver, meaning attacker-controlled data is used directly as a kernel-space pointer, enabling arbitrary writes into kernel memory - a classic and highly reliable LPE primitive. No public exploit code has been identified at time of analysis, and this CVE does not appear in the CISA KEV catalog.
