AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The vendor advisory confirms that this issue has been resolved in updated kernel releases. Users should update to the fixed kernel versions and reboot to apply the changes.
Description
A vulnerability in the Linux kernel's bnxt_en driver related to the XDP_TX action in bnxt_rx_xdp() has been fixed. The issue involved incorrect clearing of event flags, which could cause the TX ring to stall without notifying the hardware, leading to dropped packets as the RX ring would eventually become empty. The fix ensures event flags are only cleared after successful transmission calls, preventing the driver from dropping packets due to stalled TX rings.
