NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel6.12 package and not the kernel6.12 package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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.
