UBUNTU-CVE-2026-53133

In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Fix truncation for block sizes = 4G When the iommu is used the linearization of the mapping can give a single block that is very large split across multiple SG entries. When rdmablockiternext reassembles the split SG...

CVE-2026-53229

The CVE-2026-53229 issue concerns the Linux kernel mlx5e driver: on XDP_TX transmit failure, DMA mappings are not properly unmapped and XDP frames are not freed, causing a potential DMA/resource leak. The description specifies that in mlx5e_xmit_xdp_buff(), when sq->xmit_xdp_frame() returns fa...

CVE-2026-53217

The CVE-2026-53217 issue affects the Linux kernel MVPP2 driver: RX data was synchronized at the hardware packet offset, leaving end-of-frame data possibly stale on non‑coherent DMA. Root cause is incorrect DMA sync range (starting at dma_addr and not covering the actual written packet tail). The ...

EUVD-2026-39306

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...
