How to fix?

Upgrade SLES:15.6 kernel-source to version 6.4.0-150600.23.84.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source 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:

crypto: api - Use work queue in crypto_destroy_instance

The function crypto_drop_spawn expects to be called in process context. However, when an instance is unregistered while it still has active users, the last user may cause the instance to be freed in atomic context.

Fix this by delaying the freeing to a work queue.
