CVE-2025-71131
Estado: ModificadaMedia (5.5)—
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.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
