  "description": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: unset the binding mark of a reused connection  Steve French reported null pointer dereference error from sha256 lib. cifs.ko can send session setup requests on reused connection. If reused connection is used for binding session, conn-\u003Ebinding can still remain true and generate_preauth_hash() will not set sess-\u003EPreauth_HashValue and it will be NULL. It is used as a material to create an encryption key in ksmbd_gen_smb311_encryptionkey. -\u003EPreauth_HashValue cause null pointer dereference error from crypto_shash_update().
