Description
A vulnerability in the Linux kernel's rtl8723bs staging driver caused out-of-bounds (OOB) reads in the rtw_get_wps_ie() function. The function iterates over information element (IE) data from network frames without sufficient bounds checking, leading to potential memory access beyond the buffer limits. This issue has been fixed by adding bounds checks to ensure the IE header and payload fit within the buffer before access.
