{"id":"CVE-2023-53148","summary":"igb: Fix igb_down hung on surprise removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nigb: Fix igb_down hung on surprise removal\n\nIn a setup where a Thunderbolt hub connects to Ethernet and a display\nthrough USB Type-C, users may experience a hung task timeout when they\nremove the cable between the PC and the Thunderbolt hub.\nThis is because the igb_down function is called multiple times when\nthe Thunderbolt hub is unplugged. For example, the igb_io_error_detected\ntriggers the first call, and the igb_remove triggers the second call.\nThe second call to igb_down will block at napi_synchronize.\nHere's the call trace:\n    __schedule+0x3b0/0xddb\n    ? __mod_timer+0x164/0x5d3\n    schedule+0x44/0xa8\n    schedule_timeout+0xb2/0x2a4\n    ? run_local_timers+0x4e/0x4e\n    msleep+0x31/0x38\n    igb_down+0x12c/0x22a [igb 6615058754948bfde0bf01429257eb59f13030d4]\n    __igb_close+0x6f/0x9c [igb 6615058754948bfde0bf01429257eb59f13030d4]\n    igb_close+0x23/0x2b [igb 6615058754948bfde0bf01429257eb59f13030d4]\n    __dev_close_many+0x95/0xec\n    dev_close_many+0x6e/0x103\n    unregister_netdevice_many+0x105/0x5b1\n    unregister_netdevice_queue+0xc2/0x10d\n    unregister_netdev+0x1c/0x23\n    igb_remove+0xa7/0x11c [igb 6615058754948bfde0bf01429257eb59f13030d4]\n    pci_device_remove+0x3f/0x9c\n    device_release_driver_internal+0xfe/0x1b4\n    pci_stop_bus_device+0x5b/0x7f\n    pci_stop_bus_device+0x30/0x7f\n    pci_stop_bus_device+0x30/0x7f\n    pci_stop_and_remove_bus_device+0x12/0x19\n    pciehp_unconfigure_device+0x76/0xe9\n    pciehp_disable_slot+0x6e/0x131\n    pciehp_handle_presence_or_link_change+0x7a/0x3f7\n    pciehp_ist+0xbe/0x194\n    irq_thread_fn+0x22/0x4d\n    ? irq_thread+0x1fd/0x1fd\n    irq_thread+0x17b/0x1fd\n    ? irq_forced_thread_fn+0x5f/0x5f\n    kthread+0x142/0x153\n    ? __irq_get_irqchip_state+0x46/0x46\n    ? kthread_associate_blkcg+0x71/0x71\n    ret_from_fork+0x1f/0x30\n\nIn this case, igb_io_error_detected detaches the network interface\nand requests a PCIE slot reset, however, the PCIE reset callback is\nnot being invoked and thus the Ethernet connection breaks down.\nAs the PCIE error in this case is a non-fatal one, requesting a\nslot reset can be avoided.\nThis patch fixes the task hung issue and preserves Ethernet\nconnection by ignoring non-fatal PCIE errors.","modified":"2026-04-02T09:43:42.161564Z","published":"2025-09-15T14:03:10.395Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03614-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4141-1","SUSE-SU-2026:0473-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53148.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/004d25060c78fc31f66da0fa439c544dda1ac9d5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/124e39a734cb90658b8f0dc110847bbfc6e33792"},{"type":"WEB","url":"https://git.kernel.org/stable/c/39695e87d86f0e7d897fba1d2559f825aa20caeb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/41f63b72a01c0e0ac59ab83fd2d921fcce0f602d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/994c2ceb70ea99264ccc6f09e6703ca267dad63c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2312e1d12b1c3ee4100c173131b102e2aed4d04"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c9f56f3c7bc908caa772112d3ae71cdd5d18c257"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa92c463eba75dcedbd8d689ffdcb83293aaa0c3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53148.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53148"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"9d5c824399dea881779d78a6c147288bf2dccb6b"},{"fixed":"c2312e1d12b1c3ee4100c173131b102e2aed4d04"},{"fixed":"124e39a734cb90658b8f0dc110847bbfc6e33792"},{"fixed":"c9f56f3c7bc908caa772112d3ae71cdd5d18c257"},{"fixed":"994c2ceb70ea99264ccc6f09e6703ca267dad63c"},{"fixed":"fa92c463eba75dcedbd8d689ffdcb83293aaa0c3"},{"fixed":"39695e87d86f0e7d897fba1d2559f825aa20caeb"},{"fixed":"41f63b72a01c0e0ac59ab83fd2d921fcce0f602d"},{"fixed":"004d25060c78fc31f66da0fa439c544dda1ac9d5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53148.json"}}],"schema_version":"1.7.5"}
