CVE-2026-43208

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists where the set rps cpu() function incorrectly assumes that the Receive Packet Steering (RPS) table for each receive queue is of a constant size and does not change. By passing flow id to set rps cpu() based on a value computed by get rps cpu(), the system is susceptible to out-of-bound access and potential system crashes.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
