A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.
Mitigation
This flaw can be mitigated by preventing the affected xt_sctp kernel module from being loaded. For instructions on how to blacklist a kernel module, please see <https://access.redhat.com/solutions/41278>.
