CVE-2026-64020: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dmavecs leak on p2p memory We don't unmap P2P memory, so we don't need to track it. The dmavec allocation was getting leaked on the completion...

PT-2026-61336

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...

CVE-2026-64019: Undefined Security Weakness

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...

PT-2026-61337

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...
