Severity ?

7.0 (High) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

Details

A buffer overflow vulnerability was found in the NVM Express (NVMe) driver in the Linux kernel. An unprivileged user could specify a small meta buffer and let the device perform larger Direct Memory Access (DMA) into the same buffer, overwriting unrelated kernel memory, causing random kernel crashes and memory corruption.
