EUVD-2026-45615

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Check BAR resources before exporting a DMABUF A DMABUF exports access to BAR resources and, although they are requested at startup time, we need to ensure they really were reserved before exporting. Otherwise, it's...

CVE-2026-64042

The CVE-2026-64042 issue affects the Linux kernel’s VFIO PCI path, where a DMABUF export could reveal BAR resources that were not properly reserved. The root cause is a missing guard in the DMABUF-creation path, allowing access to unreserved BAR resources via the export. The public description no...

CVE-2026-64034

The CVE concerns the Linux kernel net: mana TOCTOU in hwc_msg_id handling. In mana_hwc_rx_event_handler(), resp->response.hwc_msg_id is read from DMA-coherent memory and bounds-checked, then mana_hwc_handle_resp() re-reads the same field from the same DMA buffer for test_bit() and pointer arit...

CVE-2026-64034 net: mana: Fix TOCTOU double-fetch of hwc_msg_id from DMA buffer

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix TOCTOU double-fetch of hwcmsgid from DMA buffer In manahwcrxeventhandler, resp-response.hwcmsgid is read from DMA-coherent memory and bounds-checked, then manahwchandleresp re-reads the same field from the same DMA...

CVE-2026-63910

The CVE-2026-63910 entry describes a Linux kernel vulnerability in dma-buf: a slab-use-after-free (UAF) in the dma_buf_fd() tracepoint. The fault arises because FD_ADD() leaves the allocated file descriptor live in the table; a racing thread can close() the fd before the DMA_BUF_TRACE() tracepoin...

PT-2026-61462

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the wilc wlan firmware download function when a bus acquire failure happens. The function allocates a dma buffer using kmalloc, but an early error path uses a...

PT-2026-61441

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the net devmem bind dmabuf function where the system trusts dmabuf-size and sg dma len to be multiples of PAGE SIZE without verification. This leads to two primary...

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...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

Linux Distros Unpatched Vulnerability : CVE-2026-52951

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - drm/xe/dma-buf: handle empty bo and UAF races There look to be some nasty races here when triggering the invalidatemappings hook: 1 We do xeboalloc followed by...

SUSE CVE-2026-52950

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init d...

CVE-2026-53146

CVE-2026-53146 affects the Linux kernel Thunderbolt XDomain handling. tb_xdomain_copy() copies req->response_size bytes from the received packet buffer regardless of the actual frame size, allowing a short response to read past valid frame data into stale DMA contents. The fixed behavior is to...
