CVE-2024-3447: Netapp Hci Compute Node

Medium severity, CVSS 6.0. EPSS: 0.6% chance of exploitation in the next 30 days.

A heap-based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s->data_count` and the size of `s->fifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.
