Title
staging: rtl8723bs: fix OOB reads in rtw_get_wps_ie()
Summary
In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix OOB reads in rtw_get_wps_ie() rtw_get_wps_ie() iterates over IE data from network frames without validating that the IE header and payload fit within the remaining buffer before reading them. Specifically: - in_ie[cnt + 1] is read without checking cnt + 1 < in_len - memcmp(&in_ie[cnt + 2], ...) accesses cnt + 2 without bounds check - in_ie[cnt + 1] is used as length without verifying payload fits Add bounds checks at the top of the loop body to break early if fewer than 2 bytes remain for the IE header, or if the declared payload extends past the end of the buffer. Also require at least 4 bytes of payload before comparing the WPS OUI.
Severity
No CVSS data available.
