The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.

BDU FSTEC	The vulnerability of the sdhci_sdma_transfer_multi_blocks() procedure in the QEMU hardware emulation software allows a attacker to cause a service failure or an unexpected termination of the application. Additionally, it enables the execution of arbitrary code.	21 Apr 202100:00	–	bdu_fstec
BDU FSTEC	The vulnerability of the flatview_read_continue() module of the QEMU hardware emulation software lies in the ability to write beyond the buffer boundaries. This allows attackers to access confidential data, compromise its integrity, and cause service failures.	27 Oct 202100:00	–	bdu_fstec
