CVE-2026-31431 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data.

Get rid of all the complexity added for in-place operation and just copy the AD directly.
