Title
smb: client: fix NULL ptr deref in crypto_aead_setkey()
Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix NULL ptr deref in crypto_aead_setkey()
Neither SMB3.0 or SMB3.02 supports encryption negotiate context, so
when SMB2_GLOBAL_CAP_ENCRYPTION flag is set in the negotiate response,
the client uses AES-128-CCM as the default cipher. See MS-SMB2
3.3.5.4.
Commit b0abcd65ec54 ("smb: client: fix UAF in async decryption") added
a @server->cipher_type check to conditionally call
smb3_crypto_aead_allocate(), but that check would always be false as
@server->cipher_type is unset for SMB3.02.
Fix the following KASAN splat by setting @server->cipher_type for
SMB3.02 as well.
mount.cifs //srv/share /mnt -o vers=3.02,seal,...

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
