Astra Linux – Vulnerability in Qemu

A reentrancy issue related to DMA was discovered in the Tulip device emulation in QEMU. When Tulip reads from or writes to the rx/tx descriptor, or copies a 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...
