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...

CVE-2026-72095

A flaw was found in the Linux kernel's dma-fence component. The dmafencededuparray function incorrectly handles zero-count input, leading to a memory corruption vulnerability. A local attacker could potentially exploit this by triggering specific conditions in the amdgpuuserqwait functions, which...

CVE-2026-72094

A flaw was found in the Linux kernel's dma-fence subsystem. This vulnerability arises from a timing issue on weakly ordered platforms, where memory operations related to fence signaling and pointer nullification can occur out of order. This can lead to a NULL pointer dereference, potentially...

CVE-2026-72064

A flaw was found in the Linux kernel's mana network driver. When the driver allocates receive RX buffers from page pool fragments, it fails to perform an explicit synchronization for the CPU. This oversight can lead to data integrity issues or system instability on systems configured to require...

CVE-2026-72059

A flaw was found in the Linux kernel's net: wwan: t7xx component. This issue occurs during the initialization of the Cellular Direct Memory Access CLDMA module. If the setup of the transmit or receive rings fails, a dedicated memory resource, known as a Direct Memory Access DMA pool, is not...

CVE-2026-68466

A flaw was found in the Linux kernel's lpc32xxslc driver, which manages NAND flash memory. This vulnerability occurs because the driver fails to properly handle Direct Memory Access DMA transfer timeouts. When a DMA transfer times out, the driver incorrectly reports it as successful and unmaps th...

CVE-2026-72088

A flaw was found in the Linux kernel's hpsa SCSI driver. When a physical disk is in a reset state, the driver fails to properly unmap Direct Memory Access DMA resources. This oversight can lead to a DMA mapping leak, potentially causing resource exhaustion over time...

CVE-2026-74491

A flaw was found in the Linux kernel. A null pointer dereference vulnerability exists within the ofpcirangeparserone function. This occurs when ofmatchbus returns a null value for nodes with specific range properties, which is then improperly dereferenced. An attacker could potentially exploit th...

kernel: iommu: disable SVA when CONFIG_X86 is set

A security vulnerability was found in the Linux kernel's IOMMU Shared Virtual Addressing SVA implementation on x86 architecture. When SVA is enabled, the IOMMU caches kernel page table entries. Since the kernel lacks a mechanism to notify the IOMMU when kernel page table pages are freed and...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

CVE-2026-74440

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Wait on external BO kernel fences in exec IOCTL Before arming a user job, xeexecioctl only added the VM's dma-resv KERNEL slot as a dependency. That slot covers rebinds and the kernel operations of the VM's private BOs, b...

CVE-2026-74396

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix UMR XLT cleanup on ODP populate failure mlx5rumrupdatexlt allocates and DMA maps an XLT buffer with mlx5rumrcreatexlt. The buffer is released by the common cleanup path through mlx5rumrunmapfreexlt. After...

UBUNTU-CVE-2026-74551

In the Linux kernel, the following vulnerability has been resolved: hwmon: nzxt-smart2 DMA-align output buffer Sashiko reports: When sendoutputreport calls hidhwoutputreport, the underlying USB HID core calls usbinterruptmsg which maps this buffer directly for DMA. When the DMA mapping flushes or...

UBUNTU-CVE-2026-74415

In the Linux kernel, the following vulnerability has been resolved: spi: atcspi200: fix use-after-free when driver unbind DMA resource is initialized after SPI controller registration. So when driver unbind, this can trigger a use-after-free when DMA is torn down while the controller is still ali...

UBUNTU-CVE-2026-74498

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix DMA buffer out-of-bounds write when fillmax is set When a USB audio endpoint requests full packet transfers via the fillmax descriptor flag, dataepsetparams promotes ep-curpacksize to ep-maxpacksize. However,...

UBUNTU-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...

UBUNTU-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 ...

UBUNTU-CVE-2026-72095

In the Linux kernel, the following vulnerability has been resolved: dma-fence: Make dmafencededuparray robust against 0-count input dmafencededuparray returns 1 when called with numfences == 0: the for-loop body never executes, j stays at 0, and the final return ++j yields 1. This contradicts bot...
