Summary
staging: rtl8723bs: fix potential out-of-bounds read in rtw_restruct_wmm_ie
Details

In the Linux kernel, the following vulnerability has been resolved:

staging: rtl8723bs: fix potential out-of-bounds read in rtwrestructwmm_ie

The current code checks 'i + 5 < inlen' at the end of the if statement. However, it accesses 'inie[i + 5]' before that check, which can lead to an out-of-bounds read. Move the length check to the beginning of the conditional to ensure the index is within bounds before accessing the array.
