"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix server->total_read for compound encrypted PDUs\n\nIn receive_encrypted_standard(), server->total_read is left at the\nfull decrypted frame size when walking sub-PDUs of a compound encrypted\nframe. As a result, cifs_handle_standard() passes this full size\nto smb2_check_message(), causing the PDU length guards to incorrectly\nvalidate the entire compound frame instead of the current sub-PDU.\n\nThis allows truncated non-last sub-PDUs to bypass length validation,\nleading to out-of-bounds reads in smb2_get_data_area_len().\n\nFix this by setting server->total_read to the true length of the\ncurrent sub-PDU: next_cmd for non-last sub-PDUs, and the remaining\npdu_length for the last one."
