A flaw was identified in the Linux kernel’s net/net_failover networking code where the failover transmit queue (txq) count was initialized to 16, but under certain conditions the primary device’s transmit queue index could exceed this limit. If a packet is transmitted on a failover device and the primary device’s queue index is greater than the default 16,triggering a kernel backtrace and unexpected execution paths.
