      "title": "media: ti: vpe: quiesce overflow recovery before freeing streams",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: ti: vpe: quiesce overflow recovery before freeing streams\n\nThe VIP overflow recovery worker is armed from the hardirq handler when a\nFIFO overflow is detected, and the list-complete path looks the stream up\nthrough the VPDMA list private pointer. Both keep touching stream, port\nand device state; the recovery worker also resets the parser and VPDMA,\nrepopulates the descriptor list, and re-enables the per-list IRQs.\n\nvip_stop_streaming() masks and clears the per-list IRQs, but it neither\nsynchronizes the hardirq handler nor disables recovery_work. An overflow\nIRQ that has already queued recovery_work, or a list-complete IRQ in\nflight when the stream is torn down, can therefore still dereference the\nstream after its resources are released: the descriptor list is freed by\nvip_release_stream() on file release, and the stream itself by\nfree_stream() on unbind/remove.\n\nDrain the recovery worker and the IRQ handler at both teardown points\nthrough a shared vip_quiesce_stream() helper, before any stream-owned\nresource is released. disable_work_sync() cancels pending recovery_work,\ndrains a running instance, and raises its disable depth, so a subsequent\nschedule_work() issued by a racing IRQ handler is rejected at the\nworkqueue scheduler: recovery_work cannot be requeued after\ndisable_work_sync() takes effect. The worker may still re-enable the\nper-list IRQs before disable_work_sync() returns; disable_irqs() then\nmasks those sources and synchronize_irq() waits for any in-flight handler\nthat still dereferences stream state. In vip_stop_streaming() the helper\nruns before the parser is stopped, since a worker drained by\ndisable_work_sync() may re-enable the parser before exiting and would\notherwise undo the stop. recovery_work is created disabled and enabled in\nvip_start_streaming() before IRQs, pairing the enable with the teardown\ndisable across the streaming lifecycle.\n\nThis issue was found by an in-house static analysis tool and confirmed\nby manual code review.",
