[PATCH 0/2] staging: rtl8723bs: fix two remote frame-handling bugs

[Shayaun Nejad]

Fix two rtl8723bs receive-side bugs reachable while handling remote
802.11 management frames.

The first patch fixes a use-after-free in validate_80211w_mgmt(),
where decryptor() can release the receive frame and return NULL before
the caller reuses cached pointers into that frame.

The second patch bounds the combined SUPP_RATES and EXT_SUPP_RATES IE
lengths copied from beacon/probe response data into the 16-byte
support_rate[] stack buffer in rtw_check_beacon_data().

Both issues were found by Kuzushi + deep-audit (Sonnet 4.6) and
manually verified against mainline.
