CVE-2025-22006

Medium

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: am65-cpsw: Fix NAPI registration sequence Registering the interrupts for TX or RX DMA Channels prior to registering their respective NAPI callbacks can result in a NULL pointer dereference. This is seen in practice as a random occurrence since it depends on the randomness associated with the generation of traffic by Linux and the reception of traffic from the wire.
