About this tag
The tag 'aead out of place' refers to a security fix in the Linux kernel's algif_aead subsystem, specifically CVE-2026-31431. This fix reverts the AEAD (Authenticated Encryption with Associated Data) code to out-of-place operation, removing unnecessary in-place complexity that provided no real benefit due to different source and destination memory mappings. The change simplifies the code path, which is often a key hardening step in kernel crypto subsystems. Discussions on WindowsForum.com cover this Linux kernel vulnerability and its implications for system security, focusing on the technical details of the fix and its importance for maintaining robust encryption handling in the kernel.
