A vulnerability in the Linux kernel IFB (Intermediate Functional Block) network driver was resolved. The issue involved inconsistent use of queue counts when reporting ethtool statistics, leading to out-of-bounds memory reads. Specifically, the ethtool stats callbacks used dev->real_num_rx_queues and dev->real_num_tx_queues, while the allocation was based on dev->num_tx_queues. This mismatch could cause reading beyond allocated memory, resulting in a slab-out-of-bounds error. The flaw was confirmed with KASAN under UML. The patch ensures consistent use of dev->num_tx_queues for stats reporting, preventing memory over-read.
