Pending analysis

Type:

CWE-122 Heap-based Buffer Overflow

Publication date:

14/11/2024

Last modified:

Description

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.
