In the Linux Kernel before versions 4.20.8 and 4.19.21 a use-after-free error in the "sctp_sendmsg()" function (net/sctp/socket.c) when handling SCTP_SENDALL flag can be exploited to corrupt memory.
A use-after-free issue was found in the Linux kernel's SCTP implementation. The issue 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 a denial of service or potentially escalate privileges on a system.

CVE-2019-8956 Kernel: SCTP: use-after-free while traversing list of endpoint associations
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.
