| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nidpf: fix adapter NULL pointer dereference on reboot\n\nWith SRIOV enabled, idpf ends up calling into idpf_remove() twice.\nFirst via idpf_shutdown() and then again when idpf_remove() calls into\nsriov_disable(), because the VF devices use the idpf driver, hence the\nsame remove routine. When that happens, it is possible for the adapter\nto be NULL from the first call to idpf_remove(), leading to a NULL\npointer dereference.\n\necho 1 > /sys/class/net/<netif>/device/sriov_numvfs\nreboot\n\nBUG: kernel NULL pointer dereference, address: 0000000000000020\n...\nRIP: 0010:idpf_remove+0x22/0x1f0 [idpf]\n...\n? idpf_remove+0x22/0x1f0 [idpf]\n? idpf_remove+0x1e4/0x1f0 [idpf]\npci_device_remove+0x3f/0xb0\ndevice_release_driver_internal+0x19f/0x200\npci_stop_bus_device+0x6d/0x90\npci_stop_and_remove_bus_device+0x12/0x20\npci_iov_remove_virtfn+0xbe/0x120\nsriov_disable+0x34/0xe0\nidpf_sriov_configure+0x58/0x140 [idpf]\nidpf_remove+0x1b9/0x1f0 [idpf]\nidpf_shutdown+0x12/0x30 [idpf]\npci_device_shutdown+0x35/0x60\ndevice_shutdown+0x156/0x200\n...\n\nReplace the direct idpf_remove() call in idpf_shutdown() with\nidpf_vc_core_deinit() and idpf_deinit_dflt_mbx(), which perform\nthe bulk of the cleanup, such as stopping the init task, freeing IRQs,\ndestroying the vports and freeing the mailbox. This avoids the calls to\nsriov_disable() in addition to a small netdev cleanup, and destroying\nworkqueues, which don't seem to be required on shutdown." |
