Summary

In the Linux kernel, RCU protection was added for the conventional zones bitmap of a disk (conv_zones_bitmap) in the block layer. This prevents invalid memory references during disk revalidation.

Risk Assessment

Lack of RCU protection could lead to use-after-free during disk zone configuration changes, potentially causing system crashes.

Recommendation

Apply a Linux kernel update that includes the fix for the block layer.
