Summary
bpf: Sync pending IRQ work before freeing ring buffer
Details

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

bpf: Sync pending IRQ work before freeing ring buffer

Fix a race where irqwork can be queued in bpfringbufcommit() but the ring buffer is freed before the work executes. In the syzbot reproducer, a BPF program attached to schedswitch triggers bpfringbufcommit(), queuing an irqwork. If the ring buffer is freed before this work executes, the irqwork thread may accesses freed memory. Calling irq_work_sync(&rb->work) ensures that all pending irq_work complete before freeing the buffer.
