CVE-2026-72134

A flaw was found in the Linux kernel's Serial Peripheral Interface SPI driver for i.MX systems. When a Direct Memory Access DMA transfer cannot be started, the system attempts to use a Programmed Input/Output PIO transfer instead. However, the SPI controller is not correctly reconfigured for PIO...

CVE-2026-72134

The CVE describes a Linux kernel issue in the i.MX ECSPI driver: when a DMA transfer is not possible, the driver falls back to PIO but does not undo prior DMA settings (CTRL.SMC, dynamic_burst), causing data corruption on subsequent PIO transfers. The root cause is that, if dmaengine_prep_slave_s...

CVE-2022-4994

CVE-2022-4994 concerns a Linux kernel KVM/x86 issue where the fast IN path for in-kernel PIO was adjusted. The change routes fast PIO through __emulator_pio_in() directly instead of bouncing via emulator_pio_in(), since __emulator_pio_in() now fills the required value and vcpu->arch.pio.count ...
