Keith informa un use-after-free cuando ocurre un evento de DPC simult\u00e1neamente con la eliminaci\u00f3n en caliente del mismo. parte de la jerarqu\u00eda: dpc_handler() espera que el bus secundario est\u00e9 listo debajo del puerto descendente donde ocurri\u00f3 el evento DPC. Para hacerlo, sondea el espacio de configuraci\u00f3n del primer dispositivo secundario en el bus secundario. Si ese dispositivo secundario se elimina simult\u00e1neamente, los accesos a su estructura pci_dev hacen que el kernel falle. Esto se debe a que pci_bridge_wait_for_secondary_bus() no mantiene una referencia en el dispositivo secundario. Antes de v6.3, la funci\u00f3n solo se llamaba al reanudar desde la suspensi\u00f3n del sistema o al reanudar el tiempo de ejecuci\u00f3n. Mantener una referencia no era necesario en aquel entonces porque el subproceso pciehp IRQ nunca pod\u00eda ejecutarse al mismo tiempo. (Al reanudar desde la suspensi\u00f3n del sistema, las IRQ no se habilitan hasta despu\u00e9s de la fase resume_noirq.

El commit 53b54ad074de (\"PCI/DPC: Esperar la preparaci\u00f3n del bus secundario despu\u00e9s del reinicio\"), que introdujo eso, no pudo apreciar que pci_bridge_wait_for_secundary_bus() ahora necesita mantener una referencia en el dispositivo secundario porque dpc_handler() y pciehp pueden ejecutarse simult\u00e1neamente.

Commit 53b54ad074de (\"PCI/DPC: Await readiness\nof secondary bus after reset\"), which introduced that, failed to\nappreciate that pci_bridge_wait_for_secondary_bus() now needs to hold a\nreference on the child device because dpc_handler() and pciehp may\nindeed run concurrently. The commit was backported to v5.10+ stable\nkernels, so that's the oldest one affected.\nAdd the missing reference acquisition.\nAbridged stack trace:\nBUG: unable to handle page fault for address: 00000000091400c0\nCPU: 15 PID: 2464 Comm: irq/53-pcie-dpc 6.9.0\nRIP: pci_bus_read_config_dword+0x17/0x50\npci_dev_wait()\npci_bridge_wait_for_secondary_bus()\ndpc_reset_link()\npcie_do_recovery()\ndpc_handler()", "A use-after-free flaw was found in concurrent DPC and hot-removal in the Linux kernel.
