Overview
Affected versions of this package are vulnerable to Information Exposure via the netlink_compare_arg_init process. An attacker can recover sensitive kernel address information by manipulating NETLINK_USERSOCK port IDs and analyzing hash bucket behavior exposed through /proc/net/netlink and socket diagnostics.
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
