CVE-2024-35989

This is a vulnerability in the Linux kernel's Data Movement Accelerator (DMA) engine, specifically affecting the Intel Data Streaming Accelerator (IDXD) driver. The issue arises during the removal (rmmod) of the idxd driver on systems with only one active CPU. In such scenarios, the driver's cleanup process attempts to migrate performance monitoring unit (PMU) contexts to another CPU. However, with no other CPUs available, this leads to a kernel oops—a serious error causing the system to crash.
