From: Longpeng(Mike) <longpeng2 at huawei.com> commit b02989f37fc5e865ceeee9070907e4493b3a21e2 upstream. The system will crash when the users insmod crypto/tcrypt.ko with mode=38 ( testing "cts(cbc(aes))" ). Usually the next entry of one sg will be @sg@ + 1, but if this sg element is part of a chained scatterlist, it could jump to the start of a new scatterlist array. Fix it by sg_next() on calculation of src/dst scatterlist. Fixes: dbaf0624ffa5...
