In WibuKey for Windows before version 6.71, an untrusted pointer dereference in the WibuKey2_64.sys kernel driver for 64-bit Windows allows an attacker to exploit a write-what-where primitive, enabling local privilege escalation. This can be leveraged to execute arbitrary code, run an administrator shell, or gain full control over the system.

——1Memory corruption while processing a crafted ELF file in the Primary Bootloader.14dCVE-2026-941468.8 ALT7.3%
——2A vulnerability was found in BioStar BIOS Update Utility 1.9.7.3. This issue affects the function sub_110BC of the file BSMEM64_W10.sys of the component IOCTL Handler. The manipulation of the argument PhysicalAddress/Size results in write-what-where condition. Attacking locally is a requirement. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.28dCVE-2026-941428.8 ALT7.3%
——2A security vulnerability has been detected in BioStar Temperature Monitor Utility 1.2.1806.2200. Affected by this vulnerability is the function sub_1105C of the file BS_HWMIO64_W10.sys of the component IOCTL Handler. Such manipulation of the argument PhysicalAddress leads to write-what-where condition. The attack needs to be performed locally. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.29dCVE-2026-941298.8 ALT7.3%
——2A vulnerability was detected in BioStar VALKYRIE AURORA 2.10.2411.0800. This vulnerability affects the function sub_1105C of the file BS_RVSIO64.sys of the component IOCTL Handler. The manipulation of the argument PhysicalAddress results in write-what-where condition. The attack needs to be approached locally. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.29dCVE-2026-941288.8 ALT7.3%
——2A security vulnerability has been detected in BioStar VIVID LED DJ 4.0.2411.1500. This affects the function sub_1105C of the file BS_LED64.sys of the component IOCTL Handler. The manipulation of the argument AssociatedIrp leads to write-what-where condition. Local access is required to approach this attack. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.29dCVE-2026-48977—39.8%
——12OpenSlide is a C library for reading whole slide image files. From 3.4.1 until 4.0.1, OpenSlide's parse_level0_xml() processing in src/openslide-vendor-ventana.c accepts nonpositive row or column tile counts from a crafted Ventana BIF file. The invalid counts produce attacker-controlled relative memory offsets and allow arbitrary values to be written at those offsets, affecting all supported platforms and configurations and resulting in a crash or potential arbitrary code execution. This issue is fixed in version 4.0.1.27d
