Title
GPU DDK - RGXFWIF_SYSINIT::sCorememDataStore is untrusted
Summary
Kernel software from a non-secure operating system on a platform with Trusted Execution Environment support, may cause GPU Firmware to boot up using data from non-secure memory.
The GPU thread of control (Firmware) uses a pointer from non-secure memory belonging to the Rich Execution Environment (REE) when saving or retrieving internal data between the tightly coupled private memory to main memory. An attacker with control over the REE kernel may modify the pointer value, corrupting the data used by the GPU Firmware.

Title
GPU DDK - Integer overflow in _PMRLogicalOffsetToPhysicalOffset
Summary
An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure.

Title
GPU DDK - Unvalidated sHWPerfCtlDMABuf GPU-VA, DMA-write into FW privdata via MMU ctx 0
Summary
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory.
Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.

Title
GPU DDK - Write UAF of sync checkpoint in GPU kick function after export fence file descriptor is prematurely closed
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to manipulate the lifetimes of synchronisation objects in the kernel, leading to read/write UAFs.
During workload submission involving a fence exported by the GPU driver, the reference count of the underlying synchronisation primitive is not properly incremented. This can be exploited, by destroying the exported fence and prematurely release the underlying primitive, resulting in a potential use-after-free condition.

Title
GPU DDK - UAF read and/or write of arbitrary physical memory due to integer truncation in PMRDevPhysAddrOSMem
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an integer overflow and map two GPU virtual addresses to the same physical address. One of these virutal mappings can be freed along with the physical page, allowing for a read/write UAF via the second mapping
The second virtual mapping references a physical address that has been freed after the first virtual mapping has been freed. This allows the physical memory to be allocated (for example) by another process and read/written to.

Title
GPU DDK - libusc OOB write at TreeRemove during WebGPU shader compilation
Summary
A web page that contains unusual GPU shader code is loaded into the GPU compiler process and can trigger a write out-of-bounds write crash in the GPU shader compiler library. On certain platforms, when the compiler process has system privileges this could enable further exploits on the device.
An edge case using a very small value in GPU shader code can cause a segmentation fault in the GPU shader compiler due to am out-of-bounds write.

Title
GPU DDK - kernel<->fw CCB contains SYNC_PRIMITIVE_BLOCK firmware address without holding reference
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of resources creating a write use after free scenario.
A shared resource (memory page) managed by a CPU thread of control (driver) and accessed by a GPU thread of control (Firmware) can cause a write UAF when the CPU thread frees the resource before the GPU FW has finished accessing it.

GPU DDK - _MMU_AllocLevel error recovery paths leave dangling page table entries
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an error path leading to UAF of GPU page tables.
The vulnerability allows physical memory allocated for MMU page tables to be used after being freed. This was caused by an error path that would not cleanup properly before freeing the physical allocation.

Title
GPU DDK - RGXFWIF_SYSINIT::sCorememDataStore is untrusted
Summary
Kernel software from a non-secure operating system on a platform with Trusted Execution Environment support, may cause GPU Firmware to boot up using data from non-secure memory.
The GPU thread of control (Firmware) uses a pointer from non-secure memory belonging to the Rich Execution Environment (REE) when saving or retrieving internal data between the tightly coupled private memory to main memory. An attacker with control over the REE kernel may modify the pointer value, corrupting the data used by the GPU Firmware.

Title
GPU DDK - Integer overflow in _PMRLogicalOffsetToPhysicalOffset
Summary
An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure.

Title
GPU DDK - Unvalidated sHWPerfCtlDMABuf GPU-VA, DMA-write into FW privdata via MMU ctx 0
Summary
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory.
Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.

Title
GPU DDK - Write UAF of sync checkpoint in GPU kick function after export fence file descriptor is prematurely closed
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to manipulate the lifetimes of synchronisation objects in the kernel, leading to read/write UAFs.
During workload submission involving a fence exported by the GPU driver, the reference count of the underlying synchronisation primitive is not properly incremented. This can be exploited, by destroying the exported fence and prematurely release the underlying primitive, resulting in a potential use-after-free condition.

Title
GPU DDK - Page UAF read in PMMETA_PROTECT heap memory
Summary
Software installed and run as a non-privileged user may conduct a sequence of improper GPU system calls causing use after free, which helps in facilitating unprivileged memory access from a shader code.
Triggering failure path in the MMU mapping logic by a malicious code could lead to incomplete cleanup of an internal driver state, allowing for future unauthorized access to the contents of the physical memory.

Title
GPU DDK - UAF read and/or write of arbitrary physical memory due to integer truncation in PMRDevPhysAddrOSMem
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an integer overflow and map two GPU virtual addresses to the same physical address. One of these virutal mappings can be freed along with the physical page, allowing for a read/write UAF via the second mapping
The second virtual mapping references a physical address that has been freed after the first virtual mapping has been freed. This allows the physical memory to be allocated (for example) by another process and read/written to.

Title
GPU DDK - rgxfw_set_mips_fault_address(&psInit->sFaultPhysAddr) is untrusted
Summary
Kernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a memory read or write outside the permitted range of memory for the host kernel.
Addresses passed to the GPU Firmware can be used by the Firmware for more privileged memory accesses than are permitted by the system.

Title
GPU DDK - libusc OOB write at TreeRemove during WebGPU shader compilation
Summary
A web page that contains unusual GPU shader code is loaded into the GPU compiler process and can trigger a write out-of-bounds write crash in the GPU shader compiler library. On certain platforms, when the compiler process has system privileges this could enable further exploits on the device.
An edge case using a very small value in GPU shader code can cause a segmentation fault in the GPU shader compiler due to am out-of-bounds write.
