See How to fix? for Rocky-Linux:8 relevant fixed versions and status.
A flaw was found in the IPv4 Resource Reservation Protocol (RSVP) classifier in the Linux kernel. The xprt pointer may go beyond the linear part of the skb, leading to an out-of-bounds read in the rsvp_classify function. This issue may allow a local user to crash the system and cause a denial of service.
