CVE-2017-15115 WRITEUP HIGH WRITEUP
Linux kernel < 4.14 - Use-After-Free in SCTP Peel-Off Action
The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.
CVSS 7.8
CVE-2017-6353 WRITEUP MEDIUM WRITEUP
Linux Kernel < 4.10 - Denial of Service via SCTP Association Peel-Off
net/sctp/socket.c in the Linux kernel through 4.10.1 does not properly restrict association peel-off operations during certain wait states, which allows local users to cause a denial of service (invalid unlock and double free) via a multithreaded application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-5986.
CVSS 5.5
CVE-2021-3772 WRITEUP MEDIUM WRITEUP
Linux Kernel < 5.15.0 - Denial of Service via Spoofed SCTP Chunks
A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses.
