Vulnerability from github – Published: 2025-04-03 09:32 – Updated: 2025-04-10 18:32

Details

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.

Severity

5.5 (Medium)
