Sasha Levin 8534537d0b net: sctp: prevent writes to cookie_hmac_alg from accessing invalid memory ... [ Upstream commit 320f1a4a175e7cd5d3f006f92b4d4d3e2cbb7bb5 ] proc_dostring() needs an initialized destination string, while the one provided in proc_sctp_do_hmac_alg() contains stack garbage. Thus, writing to cookie_hmac_alg would strlen() that garbage and end up accessing invalid memory.
