CVE-2026-43386

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

State: Published
Severity: Not scored
Published: May 8, 2026
Updated: May 11, 2026
Reserved: May 1, 2026

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.
