A fix is available — apply it.

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

jffs2: check jffs2_prealloc_raw_node_refs() result in few other places

Fuzzing hit another invalid pointer dereference due to the lack of checking whether jffs2_prealloc_raw_node_refs() completed successfully. Subsequent logic implies that the node refs have been allocated.

Handle that. The code is ready for propagating the error upwards.
