Description
A flaw was found in the Linux kernel's pds_core driver. During device teardown, the driver releases Direct Memory Access (DMA) buffers without disabling bus mastering, allowing the device to continue writing to system memory after it has been freed. A local user with administrative privileges could trigger this condition to cause a use-after-free issue, resulting in memory corruption and a Denial of Service (DoS).
