An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation.

CVE-2019-15666 [MEDIUM] CWE-400 kernel: out-of-bounds array access in __xfrm_policy_unlink
kernel: out-of-bounds array access in __xfrm_policy_unlink
An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation.
A flaw was found in the Linux kernel. When xfrm policy removal occurs a system crash could occur. These policy changes generally occur through the ip command or a netlink socket.
Statement: A local privileged user (with CAP_NET_ADMIN or root) is required to exploit this condition. With this limitation, this issue is rated as Moderate.

CVE-2019-15666 kernel: out-of-bounds array access in __xfrm_policy_unlink
A flaw regarding the removal of xfrm policies from the kernel may possibly crash the system or corrupt memory or escalate privilges . Policies addition or removal is a privileged operation (usually done through the ip command) or via a netlink socket.
A local privileged user (with CAP_NET_ADMIN or root) is required to exploit this condition. With this limitation, this issue is rated as Moderate.
