In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Perform lockless command completion in abort path
While adding and removing the controller, the following call trace was observed:
WARNING: CPU: 3 PID: 623596 at kernel/dma/mapping.c:532 dma_free_attrs+0x33/0x50 CPU: 3 PID: 623596 Comm: sh Kdump: loaded Not tainted 5.14.0-96.el9.x86_64 #1 RIP: 0010:dma_free_attrs+0x33/0x50

The command was completed in the abort path during driver unload with a lock held, causing the warning in abort path. Hence complete the command without any lock held.
