Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel's SCTP (Socket Control Transport Protocol) implementation. Specifically, a null dereference can occur within the
sctp disposition function, specifically sctp sf do 5 1D ce(). This happens when new asoc->peer.adaptation ind is 0 and sctp ulpevent make authkey is 0, and sctp ulpevent make authkey() returns 0, leading to a zero value being dereferenced in the sctp ulpevent free() function.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
