Overview

Affected versions of this package are vulnerable to Deadlock in the rds_tcp_tune process. An attacker can cause a kernel deadlock or system hang by repeatedly initiating unauthenticated remote TCP connections to the RDS/TCP listener, which triggers a circular locking dependency when memory allocation occurs while holding the socket lock.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
