JSON

A NULL pointer dereference issue was found in the SCTP network protocol in net/sctp/stream_sched.c in the Linux kernel. If stream_in allocation fails, stream_out is freed, which would be accessed further. This flaw allows a local user to crash the system or potentially cause a denial of service.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
