Description

A flaw was found in the Linux kernel's networking component. An incorrect assumption about the size and immutability of the Receive Packet Steering (RPS) table could lead to an out-of-bounds memory access. This vulnerability, occurring during the computation of `flow_id` in the `set_rps_cpu()` function, could result in system crashes or other unpredictable behavior, potentially leading to a Denial of Service (DoS).
