Descriptions

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter() In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size.
But then 'rate->he_gi' is used as array index instead of 'status->he_gi'.
This can lead to go beyond array boundaries in case of 'rate->he_gi' is
not equal to 'status->he_gi' and is bigger than array size. Looks like
"copy-paste" mistake. Fix this mistake by replacing 'rate->he_gi' with 'status->he_gi'. Found by Linux Verification Center (linuxtesting.org) with SVACE.

A possible array out-of-bounds read flaw was found in the Linux kernel. This issue may lead to a crash.
