In the Linux kernel, the following vulnerability has been resolved:
netfilter: nftables: fully validate NFTDATA_VALUE on store to data registers
register store validation for NFTDATAVALUE is conditional, however, the datatype is always either NFTDATAVALUE or NFTDATAVERDICT. This only requires a new helper function to infer the register type from the set datatype so this conditional check can be removed. Otherwise, pointer to chain object can be leaked through the registers.
