Details

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

smb: client: fix NULL ptr deref in cryptoaeadsetkey()

Neither SMB3.0 or SMB3.02 supports encryption negotiate context, so when SMB2GLOBALCAP_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->ciphertype check to conditionally call smb3cryptoaeadallocate(), 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,...
