21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: igb: Do not bring the device up after non-fatal error Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal") changed igb_io_error_detected() to ignore non-fatal pcie errors in order to avoid hung task that can happen when igb_down() is called multiple times. This caused an issue when processing transient non-fatal errors. igb_io_resume(), which is called after igb_io_error_detected(), assumes that device is brought down by igb_i... • https://git.kernel.org/stable/c/124e39a734cb90658b8f0dc110847bbfc6e33792 •
