A flaw was found in the Linux kernels implementation of sctp protocol in which a remote attacker can trigger an out of bounds read with an offset of up to 64kB. This may panic the machine with a page-fault and the out-of-bounds data does not seem to be returned to the remote attacker.
For this attack to be sucessful, the kernel needs to have both the SCTP protocol module loaded and a process listening as an SCTP server.

http://seclists.org/oss-sec/2016/q4/509
Last updated 24 July 2024
drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 does not ensure that certain length values are sufficiently large, which allows remote attackers to cause a denial of service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to the (1) ozusbrx and (2) ozusbhandleepdata functions.
An use after free flaw was found in the Linux kernel SCTP implementation handled auth keys reference counting during INIT collisions.
A remote user could use this flaw to crash the system or, though unlikely, escalate their privileges on the system.
