Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: ti: am65-cpsw: Fix NULL dereference on XDP_TX

If number of TX queues are set to 1 we get a NULL pointer dereference during XDP_TX.

~# ethtool -L eth0 tx 1 ~# ./xdp-trafficgen udp -A <ipv6-src> -a <ipv6-dst> eth0 -t 2 Transmitting on eth0 (ifindex 2) [ 241.135257] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000030

Fix this by using actual TX queues instead of max TX queues when picking the TX channel in am65_cpsw_ndo_xdp_xmit().
