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 Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: nvme-pci: added a missing condition check for the existence of the mapped data. The function nvmemapdata is called when the request contains physical segments; therefore, the function nvmeunmapdata should also have the same...

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 vulnerability has been resolved: drm/amdkfd: Do not allow mapping the MMIO HDP page with large pages. In that case, we do not receive the correct offset. The GPU has an unused 4K area of the register BAR space, into which we can remap registers. We remap the HDP...
