Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the amdkfd driver where the buffer size for returning buffer object bo metadata to user space is controlled by the user. A malicious user in the render group can provi...

SUSE CVE-2026-89942

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Fix potential use-after-free in anonymous buffer release An anonymous buffer handle holds a reference to the underlying IIO device. The reference is dropped in the buffer handle's release function. If the device has...

CVE-2026-90051

CVE-2026-90051 affects the Linux kernel's TCP devmem (device memory) TX path . When NETIF_F_SG is absent, devmem TCP TX was not rejected even though it requires zero-copy; tcp_sendmsg_locked() would take the copy path and attempt to read from a dma-buf iovec, breaking invariants assumed by commit...

CVE-2026-89942: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Fix potential use-after-free in anonymous buffer release An anonymous buffer handle holds a reference to the underlying IIO device. The reference is dropped in the buffer handle's release function. If the device has...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: udmabuf: Set ubuf-sg = NULL if the creation of the sg table fails. When the user space attempts to map the dmabuf, and for some reason e.g., OOM, the creation of the sg table fails, ubuf-sg needs to be set to NULL. Otherwise, whe...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed memory leakage This patch addresses potential memory leakage and segmentation faults in the gpuvmimportdmabuf function...

kernel: vfio/pci: Check BAR resources before exporting a DMABUF

A flaw was found in the Linux kernel's vfio/pci subsystem. This vulnerability occurs because the Direct Memory Access Buffer DMABUF export mechanism does not adequately verify if Base Address Register BAR resources are properly reserved before allowing access. A local attacker could exploit this ...

kernel: vfio/pci: Clean up DMABUFs before disabling function

A flaw was found in the Linux kernel's vfio/pci subsystem. During device shutdown, an improper order of operations in cleaning up Direct Memory Access Buffers DMABUFs before disabling the function creates a brief window. In this window, a device's Base Address Registers BARs could still be access...

CVE-2026-80633

A flaw was found in the Linux kernel's iommufd component. A local user could trigger a kernel warning by releasing the last reference on a Direct Memory Access Buffer DMABUF-backed IOMMU page table without holding the necessary dmaresv lock. This missing lock operation can lead to system...

SUSE CVE-2026-72093

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix use-after-free in amdxdnagemdmabufmmap When vminsertpages fails, the error path calls vma-vmops-closevma which internally calls drmgemvmclose - drmgemobjectput, releasing the GEM object reference acquired at th...

SUSE CVE-2026-74328

In the Linux kernel, the following vulnerability has been resolved: iommufd: Destroy the pages content after detaching from dmabuf Sashiko points out this has gotten out of order, the mutex could still be in use through the dmabuf invalidation callbacks. Don't destroy any of the pages content unt...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iommufd: The content of the pages should no longer be destroyed after detaching from dmabuf. Sashiko points out that this issue was previously out of order; the mutex could still be in use through the dmabuf invalidation callback...

CVE-2026-64328

A flaw was found in the Linux kernel's USB gadget subsystem. Specifically, a DMA Direct Memory Access fence leak exists in the ffs module's ffsdmabuftransfer function. This issue causes ffsdmafence objects to be allocated without their initial reference being properly released. Repeated...
