Description
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.

Executive Summary

This vulnerability occurs in the Linux kernel's crypto API where the function crypto_drop_spawn is expected to be called in process context. However, if a crypto instance is unregistered while it still has active users, the last user might cause the instance to be freed in atomic context, which is unsafe. The fix involves delaying the freeing operation by using a work queue to ensure it happens in the correct context.

Impact Analysis

If exploited or triggered, this vulnerability could lead to improper freeing of resources in atomic context, potentially causing kernel instability, crashes, or other unpredictable behavior in systems using the affected Linux kernel crypto API.
