How to fix?

Upgrade SLES:15.6 kernel-syms-coco to version 6.4.0-15061.9.coco15sp6.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-syms-coco package and not the kernel-syms-coco package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

virtio_pmem: Check device status before requesting flush

If a pmem device is in a bad status, the driver side could wait for host ack forever in virtio_pmem_flush(), causing the system to hang.

So add a status check in the beginning of virtio_pmem_flush() to return early if the device is not activated.
