Subject: staging: rtl8712: prevent buffer overrun in recvbuf2recvframe
From: Haggai Eran <[email protected]>
commit cab462140f8a183e3cca0b51c8b59ef715cb6148 upstream.
With an RTL8191SU USB adaptor, sometimes the hints for a fragmented packet are set, but the packet length is too large. Allocate enough space to prevent memory corruption and a resulting kernel panic [1].
