CVE-2023-54166

Linux

In the Linux kernel, the following vulnerability has been resolved: igc: Fix Kernel Panic during ndo_tx_timeout callback The Xeon validation group has been carrying out some loaded tests with various HW configurations, and they have seen some transmit queue time out happening during the test. This will cause the reset adapter function to be called by igc_tx_timeout(). Similar race conditions may arise when the interface is being brought down and up in igc_reinit_locked(), an interrupt being generated, and igc_clean_tx_irq() being called to complete the TX. When the igc_tx_timeout() function...
