{"id":"CVE-2024-50040","summary":"igb: Do not bring the device up after non-fatal error","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nigb: Do not bring the device up after non-fatal error\n\nCommit 004d25060c78 (\"igb: Fix igb_down hung on surprise removal\")\nchanged igb_io_error_detected() to ignore non-fatal pcie errors in order\nto avoid hung task that can happen when igb_down() is called multiple\ntimes. This caused an issue when processing transient non-fatal errors.\nigb_io_resume(), which is called after igb_io_error_detected(), assumes\nthat device is brought down by igb_io_error_detected() if the interface\nis up. This resulted in panic with stacktrace below.\n\n[ T3256] igb 0000:09:00.0 haeth0: igb: haeth0 NIC Link is Down\n[  T292] pcieport 0000:00:1c.5: AER: Uncorrected (Non-Fatal) error received: 0000:09:00.0\n[  T292] igb 0000:09:00.0: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)\n[  T292] igb 0000:09:00.0:   device [8086:1537] error status/mask=00004000/00000000\n[  T292] igb 0000:09:00.0:    [14] CmpltTO [  200.105524,009][  T292] igb 0000:09:00.0: AER:   TLP Header: 00000000 00000000 00000000 00000000\n[  T292] pcieport 0000:00:1c.5: AER: broadcast error_detected message\n[  T292] igb 0000:09:00.0: Non-correctable non-fatal error reported.\n[  T292] pcieport 0000:00:1c.5: AER: broadcast mmio_enabled message\n[  T292] pcieport 0000:00:1c.5: AER: broadcast resume message\n[  T292] ------------[ cut here ]------------\n[  T292] kernel BUG at net/core/dev.c:6539!\n[  T292] invalid opcode: 0000 [#1] PREEMPT SMP\n[  T292] RIP: 0010:napi_enable+0x37/0x40\n[  T292] Call Trace:\n[  T292]  \u003cTASK\u003e\n[  T292]  ?
