This update for qemu fixes the following issues :

Fix out-of-bounds access issue while doing multi block SDMA (CVE-2020-25085, bsc#1176681)

Fix out-of-bounds read information disclosure in icmp6_send_echoreply (CVE-2020-10756, bsc#1172380)

QEMU BIOS fails to read stage2 loader on s390x (bsc#1186290)

Change dependency from CONFIG_VFIO back to CONFIG_LINUX (bsc#1179725)

For the record, these issues are fixed in this package already. Most are alternate references to previously mentioned issues:
(CVE-2019-15890, bsc#1149813, CVE-2020-8608, bsc#1163019, CVE-2020-14364, bsc#1175534, CVE-2020-25707, bsc#1178683, CVE-2020-25723, bsc#1178935, CVE-2020-29130, bsc#1179477, CVE-2020-29129, bsc#1179484, CVE-2021-20257, bsc#1182846, CVE-2021-3419, bsc#1182975)
