A race condition vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user process to perform improper GPU memory processing operations to cause a denial of service or disclose sensitive information. This issue affects Bifrost GPU Kernel Driver: from r12p0 through r49p5, from r50p0 through r51p0, from r54p1 through r54p2; Valhall GPU Kernel Driver: from r19p0 through r49p5, from r50p0 through r54p3, r55p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r49p5, from r50p0 through r54p3, r55p0.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A flaw exists in the MCTP (Management Component Transport Protocol) implementation where `RTM GETNEIGH` requests return uninitialized data within the padding bytes of the `ndmsg` data. This occurs because netlink data in the link, address, and neighbor response messages were not properly initialized to zero. **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** Docker Desktop versions prior to 4.62.0 **Description** An out of bounds read issue exists in the grpcfuse kernel module within the Linux VM used by Docker Desktop for Windows, Linux, and macOS. This could allow a local attacker to potentially cause harm by writing to `/proc/docker` entries. The vulnerable component is the grpcfuse kernel module. **Recommendations** Update to Docker Desktop version 4.62.0 or later.

**Name of the Vulnerable Software and Affected Versions** Arm Ltd Valhall GPU Kernel Driver versions r53p0 through r54p1 Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver versions r53p0 through r54p1 **Description** A Use After Free issue exists in the Arm Ltd Valhall GPU Kernel Driver and Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver. A local, non-privileged user process can perform improper GPU memory processing operations, potentially gaining access to already freed memory. **Recommendations** Update Valhall GPU Kernel Driver to a version later than r54p1. Update Arm 5th Gen GPU Architecture Kernel Driver to a version later than r54p1.

**Name of the Vulnerable Software and Affected Versions** Arm Ltd Valhall GPU Kernel Driver versions r53p0 through r54p1 Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver versions r53p0 through r54p1 **Description** A Use After Free issue exists in the Arm Ltd Valhall GPU Kernel Driver and Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver. A local, non-privileged user process can perform improper GPU processing operations, potentially gaining access to already freed memory. **Recommendations** Update Valhall GPU Kernel Driver to a version later than r54p1. Update Arm 5th Gen GPU Architecture Kernel Driver to a version later than r54p1.

**Name of the Vulnerable Software and Affected Versions** QEMU (affected versions not specified) **Description** A heap out-of-bounds memory read flaw was found in the virtual nvme device in QEMU. The QEMU process does not validate an offset provided by the guest before computing a host heap pointer, which is used for copying data back to the guest. This can allow an attacker to disclose arbitrary heap memory relative to an allocated buffer. The issue is related to the `nvme fdp events()` function and involves reading data beyond the boundaries of a buffer in memory. **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** Linux Kernel ksmbd (affected versions not specified) **Description** A flaw was found in the handling of SMB2 read requests in the kernel ksmbd module. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this to disclose sensitive information on affected installations of Linux. Only systems with ksmbd enabled are vulnerable. **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** Linux Kernel ksmbd module (affected versions not specified) **Description** A flaw was found in the parsing of SMB2 requests that have a transform header in the kernel ksmbd module. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this to disclose sensitive information on affected installations of Linux. Only systems with ksmbd enabled are vulnerable. **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** TP-Link Archer AX21 versions (affected versions not specified) **Description** The issue is caused by a stack-based buffer overflow in the tdpServer service of TP-Link Archer AX21 routers. This allows a remote attacker to execute arbitrary code on affected installations. The specific flaw exists within the handling of command `0x422` provided to the `tmpServer` service, resulting from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Authentication is required to exploit this vulnerability. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
