NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu-kvm-debugsource package and not the qemu-kvm-debugsource package as distributed by RHEL.
Several memory leaks were found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. They exist in contrib/vhost-user-gpu/vhost-user-gpu.c and contrib/vhost-user-gpu/virgl.c due to improper release of memory (i.e., free) after effective lifetime.
