CVE-2023-52442

CVE-2023-52442 is a Linux kernel/KSMBD issue where smb2_get_msg() could return the first command in a compound request, skipping the tree-id check if SMB2_TREE_CONNECT_HE is first. The patch fixes the logic by using ksmbd_req_buf_next() to fetch the current command within a compound request (smb2...

CVE-2023-52441

CVE-2023-52441 affects the Linux kernel ksmbd component. The vulnerability is an out-of-bounds issue in init_smb2_rsp_hdr() that occurs when a client issues an SMB2 negotiate followed by SMB1 negotiate; the code could incorrectly treat SMB1 packets as SMB2, triggering an out-of-bounds path. The a...
