CVE-2023-2177 describes a null pointer dereference vulnerability within the Stream Control Transmission Protocol (SCTP) in the Linux Kernel, specifically affecting the net/sctp/stream_sched.c component. This flaw arises when stream_in allocation fails, leading to the premature freeing and subsequent access of stream_out. With a CVSS score of 5.5 (Medium), this vulnerability can be exploited locally with low attack complexity, requiring low privileges and no user interaction, potentially causing a denial of service or system crash. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
