How to fix?

Upgrade SLES:15.3 qemu-chardev-spice to version 5.2.0-17.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-chardev-spice package and not the qemu-chardev-spice package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the QEMU process on the host.
