Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the HCI DMA dequeue path within the hci dma dequeue xfer function. This function, which is not serialized, can be invoked for multiple transfers that timeout...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the net mlx5e component resetting dmafifocc when restoring an incorrect CQ, without resetting...

SUSE CVE-2026-43146

In the Linux kernel, the following vulnerability has been resolved: media: iris: Add buffer to list only after successful allocation Move listaddtail to after dmaallocattrs succeeds when creating internal buffers. Previously, the buffer was enqueued in buffers-list before the DMA allocation. If t...

SUSE CVE-2026-43202

In the Linux kernel, the following vulnerability has been resolved: fbdev: vt8500lcdfb: fix missing dmafreecoherent fbi-fb.screenbuffer is allocated with dmaalloccoherent but is not freed if the error path is reached...

SUSE CVE-2026-43250

In the Linux kernel, the following vulnerability has been resolved: usb: chipidea: udc: fix DMA and SG cleanup in epnuke The ChipIdea UDC driver can encounter "not page aligned sg buffer" errors when a USB device is reconnected after being disconnected during an active transfer. This occurs becau...

Linux Distros Unpatched Vulnerability : CVE-2026-43146

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - media: iris: Add buffer to list only after successful allocation Move listaddtail to after dmaallocattrs succeeds when creating internal buffers. Previously, th...

CVE-2026-43250

A flaw was found in the Linux kernel's ChipIdea USB Device Controller UDC driver. A local user with a malicious USB device, or a malicious USB device itself, could exploit this by reconnecting the device during an active data transfer. This improper cleanup of Direct Memory Access DMA buffers can...

kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...

CVE-2026-43146

A flaw was found in the Linux kernel's iris media driver. When creating internal buffers, a buffer was added to a list before its Direct Memory Access DMA allocation was successfully completed. If the DMA allocation failed, a partially initialized buffer remained in the list. This could lead to a...

CVE-2025-71294

A flaw was found in the Linux kernel's drm/amdgpu component. When the SDMA System Direct Memory Access block is not enabled, the bufferfuncs are not properly initialized. This can lead to a NULL pointer dereference, potentially causing a system crash and a denial of service...

CVE-2026-43283

The CVE-2026-43283 issue is in the Linux kernel's ec_bhf Ethernet driver where error-path handling used priv->rx_buf.alloc_len as the DMA handle in dma_free_coherent(), risking improper unmapping and potential memory corruption or DoS. The fix changes the DMA handle to priv->rx_buf.alloc_ph...
