CVE-2026-98803

A flaw was found in the Linux kernel's stmmac ethernet driver. When receiving network frames larger than the primary buffer size, the Direct Memory Access DMA engine attempts to write excess data into a secondary receive buffer that is neither allocated nor mapped for regular frames. An attacker ...

CVE-2026-98592

A flaw was found in the Linux kernel's SpacemiT Ethernet driver. During network packet transmission, a failure to map packet fragments causes the driver to release memory buffers without properly clearing the corresponding hardware descriptors. A local user able to trigger transmission mapping...

Astra Linux – vulnerability in linux-6.1, linux-6.12

In the Linux kernel, the following vulnerability has been resolved: dmaengine: mmppdma: Fix race condition in mmppdmaresidue Proper locking should be added to mmppdmaresidue to prevent use-after-free conditions when accessing the descriptor list and its contents. The race condition occurs when...

Astra Linux – vulnerability in linux-6.12

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix possible wrong descriptor completion in llistabortdesc At the end of this function, d is the traversal cursor of flist; however, the code finds instead. This can lead to issues such as NULL pointer...

Astra Linux – vulnerability in linux-5.15

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Allow probe failure when workqueue cannot be enabled The workqueue is enabled when the appropriate driver is loaded and disabled when the driver is removed. Upon removal, the driver assumes that the workqueue was...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: avoid SBSA UART accessing the DMACR register The chapter “B Generic UART” in “ARM Server Base System Architecture” 1 describes a generic UART interface. Such a generic UART does not support DMA. In current cod...

CVE-2026-98344

A flaw was found in the Linux kernel's DMA Direct Memory Access engine subsystem. This vulnerability can lead to a Denial of Service DoS when a local user triggers concurrent channel acquisition and release operations. Because the dmachanput function unconditionally decrements device reference...

CVE-2026-98343

A flaw was found in the Linux kernel. A local user can exploit a use-after-free vulnerability in the Direct Memory Access DMA engine to cause a Denial of Service DoS via a system crash. The issue occurs when the channel cleanup routine attempts to access device information after the underlying...

CVE-2026-98342

A flaw was found in the Linux kernel's Direct Memory Access DMA engine subsystem. A timing flaw allows a device structure to be freed from memory while active read operations are still referencing it. A local attacker could exploit this use-after-free race condition to cause a Denial of Service D...

CVE-2026-93042

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Terminate all descriptors without callbacks The DMA Engine client documentation says in the "Terminate APIs" section of Documentation/driver-api/dmaengine/client.rst: "No callback functions will be called for...

PT-2026-94840

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the dw-edma component of the DMA Engine where the system fails to properly terminate all descriptors without callbacks. When a deferred STOP reaches the interrupt...

PT-2026-93634

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference occurs in the dw-edma component of the DMA engine. The function dw edma irq request passes the dw edma irq structure to request irq before the dw edma channel...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma: The byte counter UDMACHANRT was reset to prevent overflow. The UDMACHANRTBCNTREG registers store real-time channel byte count statistics. These registers are 32-bit hardware counters, and the driver uses...

SUSE CVE-2026-72148

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Add spinlock to protect DONEINTMASK and ABORTINTMASK The DONEINTMASK and ABORTINTMASK registers are shared by all DMA channels, and modifying them requires a read-modify-write sequence. Because this operation ...

SUSE CVE-2026-72147

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma-pcie: Reject devices without driver data dwedmapcieprobe treats the PCI device ID driverdata as the template for the controller layout and copies it unconditionally. A device bound dynamically via sysfs can mat...

SUSE CVE-2026-72475

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dma-axi-dmac: Properly free struct axidmacdesc Use axidmacfreedesc to free fully the descriptor at fail path when call axidmacallocdesc in axidmacprepperipheraldmavec...

Unity Linux 20.1050a Security Update: kernel (UTSA-2026-104602)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-104602 advisory. In the Linux kernel, the following vulnerability has been resolved: dmaengine: Fix possible use after free In dmareleasechannel, check chan-device-privatecnt after...

CVE-2026-72149

In the Linux kernel, the following vulnerability has been resolved: dmaengine: tegra: Fix burst size calculation Currently, the Tegra GPC DMA hardware requires the transfer length to be a multiple of the max burst size configured for the channel. When a client requests a transfer where the length...
