Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 4.2.2 (Operating System). This issue affects the function sctp_init of the file net/sctp/protocol.c of the component SCTP Socket Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. The summary by CVE is:

The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3 has an incorrect sequence of protocol-initialization steps, which allows local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished.

The weakness was shared 10/19/2015 (Website). The advisory is shared at security-tracker.debian.org. The identification of this vulnerability is CVE-2015-5283 since 07/01/2015. An attack has to be approached locally. A simple authentication is needed for exploitation. Technical details are known, but no exploit is available.
