{"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.
