Fixed In Version: kernel 5.17-rc4
Doc Type: If docs needed, set a value
Doc Text:
A stack overflow flaw was found in the Linux kernel’s TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.

Description Marian Rehak 2022-01-31 18:08:02 UTC 
A  remote stack overflow in the TIPC networking module. With FORTIFY_SOURCE's stricter memcpy() bounds checking, this can be exploited to cause remote DOS via kernel panic on systems using TIPC. Prior to these bounds checks, and with a canary leak (or no CONFIG_STACKPROTECTOR), this can be exploited for RCE.

Just adding a note here, that even kernel-4.18.0-373.el8 not yet built for CentOS Stream 8 is missing the fix according to the changelog at https://git.centos.org/rpms/kernel/c/7ae59b72bcca86907a4a14fadbea4d30dfeef357?branch=c8s
Despite bug #2065587 has been closed.
