"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetlabel: validate unlabeled address and mask attribute lengths\n\nnetlbl_unlabel_addrinfo_get() used the address attribute length to\ndetermine whether the attribute data could be read as an IPv4 or IPv6\naddress, but did not independently validate the corresponding mask\nattribute length. A crafted Generic Netlink request could therefore\nprovide a valid IPv4/IPv6 address attribute with a shorter mask\nattribute, which would later be read as a full struct in_addr or\nstruct in6_addr.\n\nNLA_BINARY policy lengths are maximum lengths by default, so use\nNLA_POLICY_EXACT_LEN() for the unlabeled IPv4/IPv6 address and mask\nattributes. This rejects short attributes during policy validation and\nalso exposes the exact length requirements through policy introspection."
