CVE-2023-6238

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A buffer overflow vulnerability was found in the NVM Express (NVMe) driver in the Linux kernel. This issue is related to the nvme add user metadata() function and allows a privileged user to specify a small meta buffer, enabling the device to perform larger Direct Memory Access (DMA) into the same buffer. This can overwrite unrelated kernel memory, causing random kernel crashes and memory corruption. The exploitation of this vulnerability may impact the confidentiality, integrity, and availability of protected information.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
