Description

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

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

The current code checks 'i + 5 < in_len' at the end of the if statement.
However, it accesses 'in_ie[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.
