Original source description
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix race in discovery auth updates
Separate configfs opens can concurrently update the discovery AuthMethod parameter. Both callers may free the same value in iscsi_update_param_value(), causing a double-free.
Protect the lookup and replacement with the discovery TPG access lock, as used by the other TPG configfs parameter updates.
