CVE-2026-31431  (opens in a new tab)

How to fix?

Upgrade Alpine:3.24 docker to version 29.4.3-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream docker package and not the docker package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

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.

There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.
