    Resource Server where an unprivileged local user could cause a use-after-free through a missing self-
    reference guard in the map cleanup path. A successful exploit of this vulnerability might lead to code
    execution, escalation of privileges, denial of service, information disclosure, and data tampering.
    (CVE-2026-47597)

    NVIDIA GPU Display Driver for Linux contains a vulnerability in the open-source kernel module event
    delivery path where an unprivileged local user could cause a use-after-free through a race between
    asynchronous event delivery and file close. A successful exploit of this vulnerability might lead to code
    execution, escalation of privileges, denial of service, information disclosure, and data tampering.
    (CVE-2026-47598)

    NVIDIA GPU Display Driver for Linux contains a vulnerability in the open-source kernel module where an
    unprivileged local user could cause improper preservation of memory access permissions during DMA mapping.
    A successful exploit of this vulnerability might lead to code execution, escalation of privileges, denial
    of service, information disclosure, and data tampering. (CVE-2026-47599)

    NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer where an
    error-handling path could operate on an improperly initialized resource. A successful exploit of this
    vulnerability might lead to code execution, escalation of privileges, denial of service, information
    disclosure, and data tampering. (CVE-2026-47600)

    NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the open-source kernel module
    DMA-BUF import path where an unprivileged local user could cause improper preservation of memory access
    permissions when importing a read-only buffer from another device's DMA-BUF exporter. A successful exploit
    of this vulnerability might lead to code execution, escalation of privileges, denial of service,
    information disclosure, and data tampering. (CVE-2026-47601)

    NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode driver where a
    local user can cause the driver to dereference an untrusted pointer. A successful exploit of this
    vulnerability might lead to denial of service and information disclosure. (CVE-2026-47602)

    NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode driver where a
    local user may access another process's GPU channel state due to missing authorization checks. A
    successful exploit of this vulnerability might lead to information disclosure. (CVE-2026-47603)

    NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode driver where a
    local user may access another process's GPU channel state due to missing authorization checks. A
    successful exploit of this vulnerability might lead to information disclosure. (CVE-2026-4 ...
