Vulnerability from github – Published: 2023-11-21 21:30 – Updated: 2023-11-21 21:30

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.

Severity ?

7.0 (High)
