Advisory Release Date: 2019-05-16 21:48 Pacific
Advisory Updated Date: 2019-05-20 18:12 Pacific
Severity:
Important
Issue Overview:
A flaw was found in the Linux kernel's implementation of RDS over TCP. A system that has the rds_tcp kernel module loaded (either through autoload via local process running listen(), or manual loading) could possibly cause a use after free (UAF) in which an attacker who is able to manipulate socket state while a network namespace is being torn down. This can lead to possible memory corruption and privilege escalation.(CVE-2019-11815)
