A heap-buffer-overflow vulnerability exists in the sdhci_write function of QEMU, as reported by OSS-Fuzz.

The vulnerability affects multiple specific versions of QEMU from 7.0.0 through 11.1.0-rc2 and beyond a certain commit. No CVSS score is provided, but the severity is assessed as high due to the nature of heap-buffer-overflow flaws.
