Description Alex 2023-02-13 17:42:51 UTC 
An issue was discovered in the Linux kernel through 6.1-rc8.
msb_init_disk in drivers/memstick/core/ms_block.c lacks check of the
return value of alloc_ordered_workqueue() and will cause the
NULL Pointer Dereference. Moreover, the unreleased workqueue will
cause the Memory Leak.
