      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB reads in rtw_get_sec_ie(), rtw_get_wapi_ie(), and rtw_get_wps_attr()\n\nThree IE/attribute parsing functions have missing bounds checks.\n\nrtw_get_sec_ie() and rtw_get_wapi_ie() iterate over a raw IE buffer\nwithout verifying that the header bytes (tag + length) are within the\nremaining buffer before reading them.  Additionally, rtw_get_sec_ie()\ncompares the 4-byte WPA OUI at cnt+2 without checking that at least\n6 bytes remain, and rtw_get_wapi_ie() compares a 4-byte WAPI OUI at\ncnt+6 without checking that at least 10 bytes remain.\n\nrtw_get_wps_attr() reads wps_ie[0] and wps_ie+2 unconditionally at\nentry, before verifying that wps_ielen is large enough to contain\nthe 6-byte WPS IE header (element_id + length + 4-byte OUI).  Inside\nthe attribute loop, get_unaligned_be16() is called on attr_ptr and\nattr_ptr+2 without checking that 4 bytes remain in the buffer.\n\nAdd a cnt+2 bounds check before each loop body in rtw_get_sec_ie()\nand rtw_get_wapi_ie(), guard each multi-byte comparison with a minimum\nIE length requirement, add a wps_ielen < 6 early return in\nrtw_get_wps_attr(), and add a 4-byte bounds check in its inner loop.",
