CVE-2026-46028
Published: May 27, 2026· Updated: May 27, 2026
Official Description
In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - snapshot IV for async AEAD requests
AF_ALG AEAD AIO requests currently use the socket-wide IV buffer during
request processing. For async requests, later socket activity can
update that shared state before the original request has fully
completed, which can lead to inconsistent IV handling.
Snapshot the IV into per-request storage when preparing the AEAD
request, so in-flight operations no longer depend on mutable socket
state.
Technical Analysis
CVE-2026-46028 requires local access, meaning attackers must already have a foothold on the target system.
