CVE-2026-80934

CVE-2026-80934 affects the Linux kernel WiFi driver mt76 mt7996 (and mt7992). The root cause is a TX DMA mapping leak on AddBA request action frames: these frames use a HW MAC-TXP layout, but the TX-free path incorrectly decodes them as FW-TXP, causing the unmap loop to run zero times and the DMA...

CVE-2026-72064

CVE-2026-72064 relates to the Linux kernel net: mana RX path. When frag_count > 1, RX buffers are allocated from page pool fragments and remain DMA mapped; the RX completion path omits dma_unmap_single(), so the implicit CPU sync is not performed before passing data to the networking stack. Th...

In the Linux kernel, the following vulnerability has been resolved: swiotlb: Initialize the listhead of the restricted pool when SWIOTLBDYNAMIC=y. Using restricted DMA pools CONFIGDMARESTRICTEDPOOL=y in conjunction with dynamic SWIOTLB CONFIGSWIOTLBDYNAMIC=y leads to the following crash during...

CVE-2026-23174

The CVE-2026-23174 entry concerns the Linux kernel nvme-pci subsystem. Root cause: dma_needs_unmap may switch from false to true during data-iterator mapping, and the nvme driver must preserve mapped DMA vectors for later unmapping. The fix is to allocate/unprepare storage for DMA vectors on dema...
