Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak occurs in the
nvme-pci module during the completion process. The issue arises because dma vec allocations are not properly released when P2P (Peer-to-Peer) memory is used, as the system does not unmap P2P memory and therefore does not need to track it.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
