media: ti: vpe: quiesce overflow recovery before freeing streams
In the Linux kernel, the following vulnerability has been resolved: media: ti: vpe: quiesce overflow recovery before freeing streams The VIP overflow recovery worker is armed from the hardirq handler when a FIFO overflow is detected, and the list-complete path looks the stream up through the VPDMA list private pointer. Both keep touching stream, port and device state; the recovery worker also resets the parser and VPDMA, repopulates the descriptor list, and re-enables the per-list IRQs. vip_stop_streaming() masks and clears the per-list IRQs, but it neither synchronizes the hardirq handler nor disables recovery_work. An overflow IRQ that has already queued recovery_work, or a list-complete IRQ in flight when the stream is torn down, can therefore still dereference the stream after its resources are released: the descriptor list is freed by vip_release_stream() on file release, and the stream itself by free_stream() on unbind/remove. Drain the recovery worker and the IRQ handler at both teardown points through a shared vip_quiesce_stream() helper, before any stream-owned resource is released. disable_work_sync() cancels pending recovery_work, drains a running instance, and raises its disable depth, so a subsequent schedule_work() issued by a racing IRQ handler is rejected at the workqueue scheduler: recovery_work cannot be requeued after disable_work_sync() takes effect. The worker may still re-enable the per-list IRQs before disable_work_sync() returns; disable_irqs() then ma
