https://notcve.org/view.php?id=CVE-2020-7463

In FreeBSD 12.1-STABLE before r364644, 11.4-STABLE before r364651, 12.1-RELEASE before p9, 11.4-RELEASE before p3, and 11.3-RELEASE before p13, improper handling in the kernel causes a use-after-free bug by sending large user messages from multiple threads on the same SCTP socket. The use-after-free situation may result in unintended kernel behaviour including a kernel panic. En FreeBSD versiones 12.1-STABLE anteriores a r364644, 11.4-STABLE anteriores a r364651, 12.1-RELEASE anteriores a p9, 11.4-RELEASE anteriores a p3 y 11.3-RELEASE anteriores a p13, el manejo inapropiado en el kernel causa un bug de uso de la memoria previamente liberada mediante el envío de mensajes de usuario grandes de múltiples subprocesos en el mismo socket SCTP. La situación del uso de la memoria previamente liberada puede resultar en un comportamiento del kernel no deseado, incluyendo un pánico del kernel. • http://seclists.org/fulldisclosure/2021/Apr/49 http://seclists.org/fulldisclosure/2021/Apr/50 http://seclists.org/fulldisclosure/2021/Apr/57 http://seclists.org/fulldisclosure/2021/Apr/58 http://seclists.org/fulldisclosure/2021/Apr/59 https://security.FreeBSD.org/advisories/FreeBSD-SA-20:25.sctp.asc https://support.apple.com/kb/HT212317 https://support.apple.com/kb/HT212318 https://support.apple.com/kb/HT212319 https://support.apple.com/kb/HT212321 https://support.app • CWE-416: Use After Free •
