Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-31431, dubbed "Copy Fail," is a local privilege escalation (LPE) vulnerability found within the Linux kernel's cryptographic subsystem. Specifically, it stems from a logic flaw in the `algif_aead` module of the `AF_ALG` (userspace crypto API), which leads to improper memory handling during in-place operations. This flaw allows an unprivileged local user to perform a deterministic, controlled 4-byte write into the page cache of any readable file on the system, including setuid binaries. This vulnerability has been present in Linux kernels since 2017 and impacts a wide range of major distributions, including Red Hat, SUSE, Ubuntu, and Amazon Linux. Exploitation is described as reliable, not requiring race conditions or kernel-specific offsets, and can be achieved with a small Python script. The in-memory corruption means the file on disk remains unchanged, and typical on-disk checksums would not detect the modification.

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. 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.
