staging: rtl8723bs: fix potential out-of-bounds read in rtw_restruct_wmm_ie
Published May 8, 2026

HIGHCVSS 3.1
EPSS 0.17%
Description
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.
