Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 7.0.10. Affected by this vulnerability is some unknown functionality of the component Nvme Pci. The manipulation with an unknown input leads to a allocation of resources vulnerability. The CWE definition for the vulnerability is CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. As an impact it is known to affect availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dma mapping leak on data setup error We're leaking the initial DMA mapping during iteration if we fail to allocate the tracking descriptor for both PRP and SGL. Unmap the iterator directly; we can't use the existing unmap helper because it depends on the tracking descriptor being successfully allocated, so a new one for an in-use iterator is provided. The mappings were also leaking when the driver detects an invalid bio_vec when mapping PRPs, so fix that too.

It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2026-64019 since 07/19/2026. The exploitation appears to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.
