kernel: ipv6: fix potential "struct net" leak in inet6_rtm_getaddr()

A flaw was discovered in the Linux kernel's IPv6 implementation, specifically within the inet6rtmgetaddr function. The issue arises when user space provides a valid IFATARGETNETNSID value but omits the IFAADDRESS and IFALOCAL attributes. In such cases, the function returns an -EINVAL error while...
