CVE-2026-53322

A flaw was found in the Linux kernel's vfio/pci subsystem. During device shutdown, an improper order of operations in cleaning up Direct Memory Access Buffers (DMABUFs) before disabling the function creates a brief window. In this window, a device's Base Address Registers (BARs) could still be accessed via DMABUFs even after memory space enable (MSE) is cleared. This could potentially allow a different driver to access freed resources, leading to information disclosure or unauthorized resource a
