{"id":"DEBIAN-CVE-2023-53148","details":"In the Linux kernel, the following vulnerability has been resolved:  igb: Fix igb_down hung on surprise removal  In a setup where a Thunderbolt hub connects to Ethernet and a display through USB Type-C, users may experience a hung task timeout when they remove the cable between the PC and the Thunderbolt hub. This is because the igb_down function is called multiple times when the Thunderbolt hub is unplugged. For example, the igb_io_error_detected triggers the first call, and the igb_remove triggers the second call. The second call to igb_down will block at napi_synchronize. Here's the call trace:     __schedule+0x3b0/0xddb     ? __mod_timer+0x164/0x5d3     schedule+0x44/0xa8     schedule_timeout+0xb2/0x2a4     ? run_local_timers+0x4e/0x4e     msleep+0x31/0x38     igb_down+0x12c/0x22a [igb 6615058754948bfde0bf01429257eb59f13030d4]     __igb_close+0x6f/0x9c [igb 6615058754948bfde0bf01429257eb59f13030d4]     igb_close+0x23/0x2b [igb 6615058754948bfde0bf01429257eb59f13030d4]     __dev_close_many+0x95/0xec     dev_close_many+0x6e/0x103     unregister_netdevice_many+0x105/0x5b1     unregister_netdevice_queue+0xc2/0x10d     unregister_netdev+0x1c/0x23     igb_remove+0xa7/0x11c [igb 6615058754948bfde0bf01429257eb59f13030d4]     pci_device_remove+0x3f/0x9c     device_release_driver_internal+0xfe/0x1b4     pci_stop_bus_device+0x5b/0x7f     pci_stop_bus_device+0x30/0x7f     pci_stop_bus_device+0x30/0x7f     pci_stop_and_remove_bus_device+0x12/0x19     pciehp_unconfigure_device+0x76/0xe9     pciehp_disable_slot+0x6e/0x131     pciehp_handle_presence_or_link_change+0x7a/0x3f7     pciehp_ist+0xbe/0x194     irq_thread_fn+0x22/0x4d     ? irq_thread+0x1fd/0x1fd     irq_thread+0x17b/0x1fd     ? irq_forced_thread_fn+0x5f/0x5f     kthread+0x142/0x153     ? __irq_get_irqchip_state+0x46/0x46     ? kthread_associate_blkcg+0x71/0x71     ret_from_fork+0x1f/0x30  In this case, igb_io_error_detected detaches the network interface and requests a PCIE slot reset, however, the PCIE reset callback is not being invoked and thus the Ethernet connection breaks down. As the PCIE error in this case is a non-fatal one, requesting a slot reset can be avoided. This patch fixes the task hung issue and preserves Ethernet connection by ignoring non-fatal PCIE errors.","modified":"2026-09-15T09:03:02.647141475Z","published":"2025-09-15T14:15:37.270Z","upstream":["CVE-2023-53148"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-53148"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.52-1"}]}],"versions":["6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53148.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.4.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53148.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.4.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53148.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
