A use-after-free issue was found in the Linux kernel's SCTP implementation.
It could occur while traversing a list of endpoint associations to send
a message to all of them via SCTP_SENDALL process.
A user/process could use this flaw to crash the kernel resulting in DoS
or potentially escalate privileges on a system.
Created kernel tracking bugs for this issue:
