CVE-2026-43128

Summary: CVE-2026-43128 affects the Linux kernel RDMA/umem subsystem. In ib_umem_dmabuf_get_pinned_with_dma_device(), if ib_umem_dmabuf_map_pages() fails, the code previously unpinned the dmabuf immediately while the umem_dmabuf->pinned flag remained set, causing a potential double dma_buf_unp...

CVE-2026-43128

In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Fix double dmabufunpin in failure path In ibumemdmabufgetpinnedwithdmadevice, the call to ibumemdmabufmappages can fail. If this occurs, the dmabuf is immediately unpinned but the umemdmabuf-pinned flag is still set...
