EUVD-2026-101931

The HDA audio device model did not check for zero-length Buffer Descriptor List BDL entries when starting a stream. A zero-length entry caused an out-of-bounds read or write during DMA transfer processing. BDL fields were also subject to modification by the guest after validation. A malicious gue...

CVE-2026-101310

The bhyve hypervisor contains a vulnerability in its HDA audio device model because it fails to validate zero-length Buffer Descriptor List (BDL) entries when starting a stream. This oversight, combined with the fact that BDL fields can be modified by a guest after validation, allows for an out-o...

CVE-2026-101310 Multiple vulnerabilities in bhyve device models

The HDA audio device model did not check for zero-length Buffer Descriptor List BDL entries when starting a stream. A zero-length entry caused an out-of-bounds read or write during DMA transfer processing. BDL fields were also subject to modification by the guest after validation. A malicious gue...

CVE-2026-80886

CVE-2026-80886 affects the Linux kernel MSM (Qualcomm) serial driver . A race condition occurs when concurrent writes from userspace (which initiate an asynchronous DMA transfer and release the port lock) and the kernel printk path (which grabs the lock and reconfigures the UART for PIO ) collide...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: spi: atcspi200: Fixed an use-after-free issue when the driver unbind. The DMA resource is initialized after the SPI controller is registered. Therefore, when the driver unbind occurs, this can lead to a use-after-free, especially...

CVE-2026-72134

A flaw was found in the Linux kernel's Serial Peripheral Interface SPI driver for i.MX systems. When a Direct Memory Access DMA transfer cannot be started, the system attempts to use a Programmed Input/Output PIO transfer instead. However, the SPI controller is not correctly reconfigured for PIO...

Unity Linux 20.1050e Security Update: kernel (UTSA-2026-099768)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-099768 advisory. In the Linux kernel, the following vulnerability has been resolved: spi: spi-fsl-lpspi: fix teardown order issue UAF There is a teardown order issue in the driver. T...

CVE-2026-68466 mtd: rawnand: lpc32xx_slc: fail DMA transfer on completion timeout

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: lpc32xxslc: fail DMA transfer on completion timeout lpc32xxxmitdma waits for the DMA completion callback but ignores waitforcompletiontimeout. A timed out DMA transfer is therefore unmapped and reported as successfu...

CVE-2026-68466

The CVE concerns the Linux kernel driver path mtd: rawnand: lpc32xx_slc. lpc32xx_xmit_dma() waits for a DMA completion callback but uses wait_for_completion_timeout() and can time out, causing a DMA transfer to be unmapped and reported as successful to the NAND read/write path. The fix is to retu...

CVE-2026-68466: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: lpc32xxslc: fail DMA transfer on completion timeout lpc32xxxmitdma waits for the DMA completion callback but ignores waitforcompletiontimeout. A timed out DMA transfer is therefore unmapped and reported as successfu...

CVE-2026-45204

A vulnerability exists in the GPU DDK where software running as a non-privileged user can conduct improper GPU system calls. This triggers out-of-bounds (OOB) memory access and a kernel null pointer dereference within the DmaTransfer function when pui64Address points to device memory. The null po...

UBUNTU-CVE-2026-64303

In the Linux kernel, the following vulnerability has been resolved: spi: fsl-lpspi: terminate the RX channel on TX prepare failure path When dmaengineprepslavesg fails for the TX channel, the error path terminates the TX DMA channel but leaves the RX channel running. Since the RX channel was...

CVE-2026-64303

In CVE-2026-64303, a Linux kernel vulnerability in the fsl-lpspi driver occurs when dmaengine_prep_slave_sg() fails for the TX channel: the TX path is terminated but the RX path (already submitted) continues, unmapping buffers on -EINVAL and risking memory corruption or use-after-free. The fixed ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: HDMA: Add sync read before starting the DMA transfer in remote setup The linked list elements and pointers are not stored in the same memory as the HDMA controller register. If the doorbell register is toggled...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: accel/qaic: The integer overflow checks in mapuserpages have been cleaned up. The encodedma function includes some validations for intrans-size. However, it would be clearer to move these checks to findandmapuserpages. encoded...
