NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-extra package and not the kernel-zfcpdump-modules-extra package as distributed by RHEL.

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

security/keys: fix missed RCU read section on lookup

Nicholas Carlini reports that the keyring code calls assoc_array_find() in find_key_to_update() without holding the RCU read lock, while the assoc_array_gc() code really is designed around removing the node from the tree and then freeing it after an RCU grace-period.

The regular key handling doesn't see this because holding the keyring semaphore hides any lifetime issues, but the persistent key handling uses a different model.

Instead of extending the keyring locking, just do the simple RCU locking that the assoc_array was designed for.
