Description
A double-free vulnerability was found in the Intel Xe GPU driver's NVM (non-volatile memory) initialization. When auxiliary_device_add() fails after auxiliary_device_init() succeeds, the driver incorrectly frees memory that will also be freed by the device release callback, leading to a double-free condition.
Statement
This vulnerability affects systems with Intel Xe discrete GPUs (Arc series). Exploitation requires triggering a specific error path during device initialization, which is difficult to achieve reliably. The double-free could potentially lead to memory corruption but practical exploitation for code execution is unlikely.
