Doc Text:
This is a flaw in the Linux kernel's ICE driver for Intel Ethernet controllers. The problem arises when the system enters a suspended state, and the driver frees queue vectors without resetting the num_q_vectors variable. This oversight causes the ice_rebuild() function to allocate an incorrectly sized buffer, leading to memory corruption and potential system crashes. During suspension, the driver fails to restore the num_q_vectors value after freeing queue vectors, resulting in invalid memory operations during system rebuilds. Kernel crashes or instability can occur, especially when resuming from suspension, due to buffer mismanagement.
