**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 12.1 iOS versions prior to 15.2 iPadOS versions prior to 15.2 **Description** A race condition was addressed with improved state handling, allowing a malicious application to potentially execute arbitrary code with kernel privileges. **Recommendations** For macOS versions prior to 12.1, update to macOS Monterey 12.1 or later. For iOS versions prior to 15.2, update to iOS 15.2 or later. For iPadOS versions prior to 15.2, update to iPadOS 15.2 or later.

**Name of the Vulnerable Software and Affected Versions** Windows (affected versions not specified) **Description** The issue is related to insecure privilege management in the Windows Secure Kernel Mode of Windows operating systems. It allows an attacker to elevate their privileges. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Windows Hyper-V (affected versions not specified) **Description** The issue is related to an elevation of privilege vulnerability. It occurs due to improper handling of objects in memory by Windows Hyper-V on a host server. This vulnerability can be exploited by an attacker to elevate their privileges. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: The issue is related to the create cq and create qp functions in the PVRDMA emulator of QEMU, which is associated with insufficient resource release after its valid lifetime has expired. This can be exploited by an attacker to cause a denial of service by creating CQ/QP objects. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: The issue is related to a memory leak in the `pvrdma realize` function in QEMU's PVRDMA hardware emulator. This leak occurs after an initialization error. The problem is associated with insufficient resource release after its valid lifetime has expired. Exploitation of this issue may allow an attacker to cause a denial of service. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: The issue is related to the `pvrdma idx ring has` function in the PVRDMA emulator of QEMU, which can lead to an infinite loop due to an unreachable exit condition. This can be exploited by a remote attacker to cause a denial of service. The problem arises from un-checked return values in `hw/rdma/vmw/pvrdma dev ring.c`, specifically the mishandling of `-1` return values. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: The issue is related to the hw/rdma/rdma backend.c component in QEMU, which allows guest OS users to trigger out-of-bounds access. This can be achieved via a PvrdmaSqWqe ring element with a large `num sge` value, potentially leading to a denial of service. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: The issue is related to errors in pointer dereferencing in the PVRDMA emulator hardware component of QEMU. It may allow a remote attacker to cause a denial of service by creating CQ/QP objects, potentially leading to a NULL pointer dereference or excessive memory allocation in functions such as `create cq ring` or `create qp rings`. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: The issue is related to errors in pointer dereferencing in the uar read and uar write functions of the PVRDMA emulator's virtual network adapter in QEMU. This can be exploited by a remote attacker to cause a denial of service. The problem arises because QEMU does not implement a read operation, such as uar read, which by analogy to uar write, allows attackers to cause a denial of service through a NULL pointer dereference. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Windows Subsystem for Linux versions prior to the fixed version Windows 10 versions 1703 through 1709 Windows Server, version 1709 **Description** The issue is related to the way objects are handled in memory, allowing an elevation of privilege. This could potentially enable attackers to affect the system. **Recommendations** For Windows 10 versions 1703 through 1709, update to a version that includes the fix for this issue. For Windows Server, version 1709, apply the necessary patch or update to resolve the elevation of privilege vulnerability. At the moment, there is no information about a newer version that contains a fix for this vulnerability in other affected versions.
