CVE-2023-53587

If something was written to the buffer just before destruction, it may be possible (maybe not in a real system, but it did happen in ARCH=um with time-travel) to destroy the ringbuffer before the IRQ work ran, leading this KASAN report (or a crash without KASAN):

BUG: KASAN: slab-use-after-free in irq_work_run_list+0x11a/0x13a

The buggy address belongs to the object at 000000006d640800
 which belongs to the cache kmalloc-1k of size 1024
The buggy address is located 584 bytes inside of
 freed 1024-byte region [000000006d640800, 000000006d640c00)

Add the appropriate irqworksync() so the work finishes before the buffers are destroyed.

Prior to the commit in the Fixes tag below, there was only a single global IRQ work, so this issue didn't exist.
