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

The Linux kernel's dma_map_resource() used pfn_valid() to verify a PFN range is not RAM, but this check only confirms memory map availability, not actual RAM backing. On ARM64 SPARSEMEM systems with 128MB sections, MMIO addresses sharing a section with RAM falsely triggered WARN_ON_ONCE, causing ...

PT-2026-61336

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A DMA mapping leak occurs in the nvme-pci module during data setup errors. The leak happens during iteration if the tracking descriptor for either PRP Physical Region Page or SGL Scatter...

PT-2026-61466

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the dma map resource function where a sanity check using pfn valid incorrectly identifies certain Memory-Mapped I/O MMIO addresses as RAM. On ARM64 systems using...

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 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: atlantic: Fixed the DMA mapping for PTP HWTS rings. The function aqringhwtsrxalloc maps additional AQCFGRXDSDEF bytes for PTP HWTS rings. However, the generic aqringfree function does not take this into account. To fix th...

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 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...

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...
