net: psp: require admin permission for dev-set and key-rotate
In the Linux kernel, the following vulnerability has been resolved: net: psp: require admin permission for dev-set and key-rotate The dev-set and key-rotate netlink operations modify shared device state (PSP version configuration and cryptographic key material, respectively) but do not require CAP_NET_ADMIN. The only access control is psp_dev_check_access() which merely verifies netns membership.
