CVE-2026-64149

A flaw was found in the Linux kernel's Direct Memory Access DMA mapping subsystem. On ARM64 systems configured with SPARSEMEM a memory management model, the dmamapresource function could incorrectly identify valid memory-mapped input/output MMIO addresses as random access memory RAM. This false...

CVE-2026-64019

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dma mapping leak on data setup error We're leaking the initial DMA mapping during iteration if we fail to allocate the tracking descriptor for both PRP and SGL. Unmap the iterator directly; we can't use the existing...

EUVD-2026-45834

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: move dmamapresource sanity check into debug code dmamapresource uses pfnvalid to ensure the range is not RAM. However, pfnvalid only checks for availability of the memory map for a PFN but it does not ensure that the...

CVE-2026-64149

In the Linux kernel, CVE-2026-64149 fixes a DMA mapping sanity check: dma_map_resource() previously relied on pfn_valid() to exclude RAM, but this could misclassify MMIO regions sharing a sparsemem section as usable RAM, triggering a WARN_ON_ONCE and DMA_MAPPING_ERROR on platforms like Raspberry ...

CVE-2026-53229 net/mlx5e: xsk: Fix DMA and xdp_frame leak on XDP_TX xmit failure

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix DMA and xdpframe leak on XDPTX xmit failure In the XSK branch of mlx5exmitxdpbuff, when sq-xmitxdpframe returns false e.g. XDPSQ is full, the function returns without unmapping the DMA address or freeing the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Error handling was added in xhcimapurbfordma. Currently, xhcimapurbfordma creates a temporary buffer and copies the SG list to the new linear buffer. However, if kzallocnode fails, the call to sgpcopytobuffer may lead ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: vfio/type1: prevents underflow of lockedvm via exec When a vfio container is preserved during execution, the task does not change. Instead, a new memory page is allocated with lockedvm=0, and the counter from existing DMA mapping...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: nvme-pci: Handling of changes to the device’s DMA map requirements. The initial state of dmaneedsunmap might be false, but it becomes true during the DMA mapping process. Enabling swiotlb can affect the outcome in such cases...
