Severity ?

7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: mxs-dcp - Ensure payload is zero when using key slot

We could leak stack memory through the payload field when running AES with a key from one of the hardware's key slots. Fix this by ensuring the payload field is set to 0 in such cases.

This does not affect the common use case when the key is supplied from main memory via the descriptor payload.
