How to fix?

Upgrade SLES:15.0 qemu-block-ssh to version 2.11.2-9.4.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-block-ssh package and not the qemu-block-ssh package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
