https://notcve.org/view.php?id=CVE-2022-31616
NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape, where a local user with basic capabilities can cause an out-of-bounds read, which may lead to denial of service, or information disclosure. NVIDIA GPU Display Driver para Windows contiene una vulnerabilidad en el controlador de la capa de modo kernel (nvlddmkm.sys) para DxgkDdiEscape, donde un usuario local con capacidades básicas puede provocar una lectura fuera de los límites, lo que puede provocar Denegación de Servicio (DoS) o divulgación de información. • https://nvidia.custhelp.com/app/answers/detail/a_id/5383 • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2022-21815
NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for private IOCTLs where a NULL pointer dereference in the kernel, created within user mode code, may lead to a denial of service in the form of a system crash. NVIDIA GPU Display Driver para Windows contiene una vulnerabilidad en el manejador de la capa del modo kernel (nvlddmkm.sys) para las IOCTL privadas en la que una desreferencia del puntero NULL en el kernel, creada dentro del código del modo de usuario, puede conllevar a una denegación de servicio en forma de bloqueo del sistema • https://nvidia.custhelp.com/app/answers/detail/a_id/5312 • CWE-476: NULL Pointer Dereference •
CVE-2018-3639 – AMD / ARM / Intel - Speculative Execution Variant 4 Speculative Store Bypass
https://notcve.org/view.php?id=CVE-2018-3639
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. Los sistemas con microprocesadores que emplean la ejecución especulativa y que realizan la ejecución especulativa de lecturas de memoria antes de que se conozcan las direcciones de todas las anteriores escrituras de memoria podrían permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un análisis de canal lateral. Esto también se conoce como Speculative Store Bypass (SSB), Variant 4. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://www.exploit-db.com/exploits/44695 https://github.com/mmxsrup/CVE-2018-3639 https://github.com/Shuiliusheng/CVE-2018-3639-specter-v4- https://github.com/malindarathnayake/Intel-CVE-2018-3639-Mitigation_RegistryUpdate http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00007.html http://support.lenovo.com/us/en/solutions/LEN-2213 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
