An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for frames larger than the MTU.
Se descubrió un problema en drivers/net/ethernet/intel/igb/igb_main.c en el controlador IGB en el kernel de Linux anterior a 6.5.3. Es posible que un tamaño de búfer no sea adecuado para tramas más grandes que la MTU.
A flaw was found in igb_configure_rx_ring in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel. An overflow of the contents from a packet that is too large will overflow into the kernel's ring buffer, leading to a system integrity issue.
