CVE-2023-52441 ksmbd: fix out of bounds in init_smb2_rsp_hdr()

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix out of bounds in initsmb2rsphdr If client send smb2 negotiate request and then send smb1 negotiate request, initsmb2rsphdr is called for smb1 negotiate request since needneg is set to false. This patch ignore smb1...

CVE-2023-52441

CVE-2023-52441 affects the Linux kernel ksmbd path and is resolved by a patch that fixes an out-of-bounds condition in init_smb2_rsp_hdr(). When a client sends an SMB2 negotiate request followed by an SMB1 negotiate request, init_smb2_rsp_hdr is invoked for the SMB1 path because need_neg is false...

CVE-2023-52440

CVE-2023-52440 affects the ksmbd component of the Linux kernel. Root cause: a slub overflow in ksmbd_decode_ntlmssp_auth_blob() when authblob->SessionKey.Length exceeds CIFS_KEY_SIZE, enabling overflow during key exchange (cifs_arc4_crypt copies from SessionKey). The fix introduces bounds prot...
