algif aead fix

About this tag
The algif_aead fix addresses a security vulnerability in the Linux kernel's AEAD (Authenticated Encryption with Associated Data) subsystem, tracked as CVE-2026-31431. The fix reverts the code to safer out-of-place AEAD handling, removing unnecessary in-place complexity introduced by an earlier commit. This simplification is considered a hardening step, as the source and destination buffers come from different memory mappings, making in-place operations redundant. The change preserves associated data copying while eliminating logic that could introduce security issues. For Linux users and administrators, applying this kernel update is recommended to maintain system security, particularly in environments relying on kernel crypto operations.

  1. Linux CVE-2026-31431 Fix: algif_aead Returns to Safer Out-of-Place AEAD Handling

    The Linux kernel’s algif_aead code has received a narrowly scoped but security-relevant fix in CVE-2026-31431, and the public record makes the intent unusually clear: the subsystem is being pushed back to out-of-place operation, while preserving only the copying of associated data. The advisory...
