Full vulnerability record from the local CVENow database.
Description

In the Linux kernel, the following vulnerability has been resolved: net: psample: fix info leak in PSAMPLE_ATTR_DATA psample open codes nla_put() presumably to avoid wiping the data with 0s just to override it with packet data. This open coding is missing clearing the pad, however, each netlink attr is padded to 4B and data_len may not be divisible by 4B.
