Description

A flaw was discovered in the Linux kernel's IPv6 implementation, specifically within the inet6_rtm_getaddr() function. The issue arises when user space provides a valid IFA_TARGET_NETNSID value but omits the IFA_ADDRESS and IFA_LOCAL attributes. In such cases, the function returns an -EINVAL error while inadvertently increasing the reference count of the struct net object, leading to a potential memory leak. This flaw has been addressed by ensuring that the reference count is properly managed, preventing unintended resource retention. Users are advised to update their Linux kernel to a version that includes this fix to maintain system stability and prevent resource leaks.
