  "title": "staging: rtl8723bs: fix OOB reads in rtw_get_sec_ie(), rtw_get_wapi_ie(), and rtw_get_wps_attr()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  staging: rtl8723bs: fix OOB reads in rtw_get_sec_ie(), rtw_get_wapi_ie(), and rtw_get_wps_attr()  Three IE/attribute parsing functions have missing bounds checks.  rtw_get_sec_ie() and rtw_get_wapi_ie() iterate over a raw IE buffer without verifying that the header bytes (tag \u002B length) are within the remaining buffer before reading them.  Additionally, rtw_get_sec_ie() compares the 4-byte WPA OUI at cnt\u002B2 without checking that at least 6 bytes remain, and rtw_get_wapi_ie() compares a 4-byte WAPI OUI at cnt\u002B6 without checking that at least 10 bytes remain.  rtw_get_wps_attr() reads wps_ie[0] and wps_ie\u002B2 unconditionally at entry, before verifying that wps_ielen is large enough to contain the 6-byte WPS IE header (element_id \u002B length \u002B 4-byte OUI).  Inside the attribute loop, get_unaligned_be16() is called on attr_ptr and attr_ptr\u002B2 without checking that 4 bytes remain in the buffer.  Add a cnt\u002B2 bounds check before each loop body in rtw_get_sec_ie() and rtw_get_wapi_ie(), guard each multi-byte comparison with a minimum IE length requirement, add a wps_ielen \u003C 6 early return in rtw_get_wps_attr(), and add a 4-byte bounds check in its inner loop.",
