CVE-2025-71131

crypto: seqiv - Do not use req->iv after crypto_aead_encrypt

State: Published
Severity: 7.5 High
Published: Jan 14, 2026
Updated: Oct 19, 2026
Reserved: Jan 13, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

crypto: seqiv - Do not use req->iv after crypto_aead_encrypt

As soon as crypto_aead_encrypt is called, the underlying request may be freed by an asynchronous completion. Thus dereferencing req->iv after it returns is invalid.

Instead of checking req->iv against info, create a new variable unaligned_info and use it for that purpose instead.
