CVE-2022-2962 (GCVE-0-2022-2962)

Vulnerability from cvelistv5 – Published: 2022-09-13 19:18 – Updated: 2025-04-23 17:11
VLAI
Summary
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.

When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn\u0027t check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition."
