Title
staging: rtl8723bs: properly validate the data in rtw_get_ie_ex()
Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: properly validate the data in rtw_get_ie_ex()
Just like in commit 154828bf9559 ("staging: rtl8723bs: fix out-of-bounds
read in rtw_get_ie() parser"), we don't trust the data in the frame so
we should check the length better before acting on it
Severity ?
No CVSS data available.
