The Amazon-Linux security team deemed this advisory irrelevant for Amazon-Linux:2023.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel6.18-libbpf-debuginfo package and not the kernel6.18-libbpf-debuginfo package as distributed by Amazon-Linux.
In the Linux kernel, the following vulnerability has been resolved:
net: do not pass flow_id to set_rps_cpu()
Blamed commit made the assumption that the RPS table for each receive queue would have the same size, and that it would not change.
Compute flow_id in set_rps_cpu(), do not assume we can use the value computed by get_rps_cpu(). Otherwise we risk out-of-bound access and/or crashes.
