Descriptions
In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix potential "struct net" leak in inet6_rtm_getaddr()
It seems that if userspace provides a correct IFA_TARGET_NETNSID value
but no IFA_ADDRESS and IFA_LOCAL attributes, inet6_rtm_getaddr()
returns -EINVAL with an elevated "struct net" refcount.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ipv6: soluciona una posible fuga de "struct net" en inet6_rtm_getaddr() Parece que si el espacio de usuario proporciona un valor IFA_TARGET_NETNSID correcto pero no los atributos IFA_ADDRESS e IFA_LOCAL, inet6_rtm_getaddr() devuelve -EINVAL con un recuento elevado de "estructura neta".
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.
