An issue was discovered in the Linux kernel before 5.0.9. There is a NULL pointer dereference for a cd data structure if alloc_disk fails in drivers/block/paride/pf.c.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
