How to fix?

Upgrade SLES:15.3 qemu-kvm to version 5.2.0-150300.115.2 or higher.

NVD Description

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

A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results. Affected QEMU versions <= 6.2.0.
