CVE-2026-64019

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

Description A DMA mapping leak occurs in the nvme-pci module during data setup errors. The leak happens during iteration if the tracking descriptor for either PRP (Physical Region Page) or SGL (Scatter Gather List) fails to allocate. Additionally, mappings leak when the driver detects an invalid bio vec during PRP mapping. PRP is a method used by NVMe to describe memory pages, and SGL is a list used to describe data buffers in non-contiguous memory.

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