CVE-2026-97421

The Linux kernel contains a vulnerability in the RDMA/umem subsystem related to boundary conditions in the ib_umem_find_best_pgsz() function. The root cause involves potential integer truncation and overflow issues, particularly on 32-bit systems, where umem->iova (a u64 value) may be truncate...

EUVD-2026-86034

In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Be careful about boundary conditions in ibumemfindbestpgsz Several corner cases, especially important on 32 bits: - umem-iova is u64, the function argument should pass in u64 or iova will be truncated - Check that the...

Astra Linux – Vulnerability in Linux 6.1

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