Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RISC-V: Ensure that port I/O string accessors actually work properly. Fixed port I/O string accessors such as insb’, outsb’, etc., which use the physical PCI port I/O address rather than the corresponding memory mapping to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fixed a data leak in the mmioread function. The mmioread function calls a TDVMCALL to retrieve MMIO data for a given address from the VMM. Sean noticed that mmioread inadvertently exposes the value of an initialized...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: x86/tdx: Fixed the “in-kernel MMIO” check TDX only supports MMIO operations initiated by the kernel. The handlemmio function checks whether the VE exception occurred in the kernel and rejects the operation if it did. However,...

Astra Linux – Vulnerability in Qemu

A reentrancy issue with DMA was discovered in the Tulip device emulation in QEMU. When Tulip reads from or writes to the rx/tx descriptor, or copies the rx/tx frame, it does not check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers...

CVE-2026-64429 gpio: eic-sprd: use raw_spinlock_t in the irq startup path

In the Linux kernel, the following vulnerability has been resolved: gpio: eic-sprd: use rawspinlockt in the irq startup path sprdeicirqunmask enables the GPIO IRQ and then updates controller state through sprdeicupdate, which takes sprdeic-lock with spinlockirqsave. The callback can be reached fr...

PT-2026-64570

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the dwc3 ulpi setup function where it incorrectly passes dwc3-regs to the dwc3 readl and dwc3 writel functions. These functions are designed to take the dwc3 structure...

CVE-2026-64062

A flaw was found in the Linux kernel's network filesystem netfs component. Specifically, a vulnerability in the netfsadvancewritethrough function, when operating in write-through mode, can lead to a system deadlock. This occurs because the function may not consistently unlock memory pages folios ...

CVE-2026-64186

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Remove latent out-of-bounds access in IOMMU debugfs In iommummiowrite and iommucapabilitywrite, the variables dbgmmiooffset and dbgcapoffset are declared as int. However, they are populated using kstrtou32fromuser. If ...

However, they are populated using kstrtou32fromuser. If ...

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 ...

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 dma-mapping: move dma_map_resource() sanity check into debug code

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...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: Disabling MMIO access during SMU Mode 1 reset During Mode 1 reset, the ASIC undergoes a reset cycle and becomes temporarily inaccessible via PCIe. Any attempt to access MMIO registers during this period e.g., from...
